DATASHEET

ICL3221E, ICL3222E, ICL3223E,
ICL3232E, ICL3241E, ICL3243E
The Intersil ICL32xxE devices are 3.0V to 5.5V powered
RS-232 transmitters/receivers which meet ElA/TIA-232
and V.28/V.24 specifications, even at VCC = 3.0V.
Additionally, they provide ±15kV ESD protection
(IEC61000-4-2 Air Gap and Human Body Model) on
transmitter outputs and receiver inputs (RS-232 pins).
Targeted applications are PDAs, Palmtops, and notebook
and laptop computers where the low operational, and
even lower standby, power consumption is critical.
Efficient on-chip charge pumps, coupled with manual and
automatic power-down functions (except for the
ICL3232E), reduce the standby supply current to a 1µA
trickle. Small footprint packaging, and the use of small,
low value capacitors ensure board space savings as well.
Data rates greater than 250kbps are guaranteed at worst
case load conditions. This family is fully compatible with
3.3V-only systems, mixed 3.3V and 5.0V systems, and
5.0V-only systems.
Features
• ESD Protection for RS-232 I/O Pins to ±15kV
(IEC61000)
• Drop in Replacements for MAX3221E, MAX3222E,
MAX3223E, MAX3232E, MAX3241E, MAX3243E,
SP3243E
• ICL3221E is a Low Power, Pin Compatible Upgrade
for 5V MAX221E
• ICL3222E is a Low Power, Pin Compatible Upgrade
for 5V MAX242E, and SP312E
• ICL3232E is a Low Power Upgrade for HIN232E,
ICL232 and Pin Compatible Competitor Devices
• RS-232 Compatible with VCC = 2.7V
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V
• Latch-Up Free
• On-Chip Voltage Converters Require Only Four
External 0.1µF Capacitors
• Manual and Automatic Power-Down Features
The ICL324XE are 3-driver, 5-receiver devices that
provide a complete serial port suitable for laptop or
notebook computers. Both devices also include
noninverting always-active receivers for “wake-up”
capability.
• Guaranteed Mouse Driveability (ICL324xE Only)
The ICL3221E, ICL3223E and ICL3243E, feature an
automatic power-down function which powers down
the on-chip power-supply and driver circuits. This occurs
when an attached peripheral device is shut off or the
RS-232 cable is removed, conserving system power
automatically without changes to the hardware or
operating system. These devices power up again when a
valid RS-232 voltage is applied to any receiver input.
• Low Supply Current in Power-Down State . . . . . 1µA
Table 1 summarizes the features of the devices
represented by this data sheet, while Application Note
AN9863 summarizes the features of each device
comprising the ICL32xxE 3V family.
• Receiver Hysteresis For Improved Noise Immunity
• Guaranteed Minimum Data Rate. . . . . . . . 250kbps
• Wide Power Supply Range . . . . Single +3V to +5.5V
• Pb-Free Available (RoHS Compliant)

Detailed Description
ICL32xxE interface ICs operate from a single +3V to
+5.5V supply, guarantee a 250kbps minimum data
rate, require only four small external 0.1µF capacitors,
feature low power consumption, and meet all ElA
RS-232C and V.28 specifications. The circuit is divided
into three sections: charge pump, transmitters and
receivers.
Charge-Pump
Intersil’s new ICL32xxE family utilizes regulated onchip dual charge pumps as voltage doublers, and
voltage inverters to generate ±5.5V transmitter
supplies from a VCC supply as low as 3.0V. This allows
these devices to maintain RS-232 compliant output
levels over the ±10% tolerance range of 3.3V powered
systems. The efficient on-chip power supplies require
only four small, external 0.1µF capacitors for the
voltage doubler and inverter functions at VCC = 3.3V.
See “Capacitor Selection” on page 18 and Table 3 on
page 18 for capacitor recommendations for other
operating conditions. The charge pumps operate
discontinuously (i.e., they turn off as soon as the V+
and V- supplies are pumped up to the nominal values),
resulting in significant power savings.
Transmitters
The transmitters are proprietary, low dropout, inverting
drivers that translate TTL/CMOS inputs to EIA/TIA-232
output levels. Coupled with the on-chip ±5.5V
supplies, these transmitters deliver true RS-232 levels
over a wide range of single supply system voltages.
14
Except for the ICL3232E, all transmitter outputs
disable and assume a high impedance state when the
device enters the power-down mode (see Table 2).
These outputs may be driven to ±12V when disabled.
All devices guarantee a 250kbps data rate for full load
conditions (3kΩ and 1000pF), VCC  3.0V, with one
transmitter operating at full speed. Under more typical
conditions of VCC  3.3V, RL = 3kΩ, and CL = 250pF,
one transmitter easily operates at 900kbps.
Transmitter inputs float if left unconnected, and may
cause ICC increases. Connect unused inputs to GND for
the best performance.
Receivers
All the ICL32xxE devices contain standard inverting
receivers that three-state (except for the ICL3232E)
via the EN or FORCEOFF control lines. Additionally, the
two ICL324XE products include noninverting
(monitor) receivers (denoted by the ROUTB label)
that are always active, regardless of the state of any
control lines. All the receivers convert RS-232 signals
to CMOS output levels and accept inputs up to ±25V
while presenting the required 3kΩ to 7kΩ input
impedance (see Figure 1) even if the power is off
(VCC = 0V). The receivers’ Schmitt trigger input stage
uses hysteresis to increase noise immunity and
decrease errors due to slow input signal transitions.
The ICL3221E, ICL3222E, ICL3223E, ICL3241E
inverting receivers disable only when EN is driven high.
ICL3243E receivers disable during forced (manual)
power-down, but not during automatic power-down
(see Table 2).

ICL3241E and ICL3243E monitor receivers remain
active even during manual power-down and forced
receiver disable, making them extremely useful for
Ring Indicator monitoring. Standard receivers driving
powered down peripherals must be disabled to
prevent current flow through the peripheral’s
protection diodes (see Figures 2 and 3). This renders
them useless for wake up functions, but the
corresponding monitor receiver can be dedicated to
this task as shown in Figure 3.

Low Power Operation
These 3V devices require a nominal supply current of
0.3mA, even at VCC = 5.5V, during normal operation
(not in power-down mode). This is considerably less
than the 5mA to 11mA current required by comparable
5V RS-232 devices, allowing users to reduce system
power simply by switching to this new family.
Pin Compatible Replacements for 5V
Devices
The ICL3221E, ICL3222E, ICL3232E are pin compatible
with existing 5V RS-232 transceivers - See the
“Features” section on page 1 for details.
This pin compatibility coupled with the low ICC and
wide operating supply range, make the ICL32xxE
potential lower power, higher performance drop-in
replacements for existing 5V applications. As long as
the 5V RS-232 output swings are acceptable, and
transmitter input pull-up resistors aren’t required, the
IICL32xxE should work in most 5V applications.
When replacing a device in an existing 5V application,
it is acceptable to terminate C3 to VCC as shown on
the “Typical Operating Circuits” on page 2.
Nevertheless, terminate C3 to GND if possible, as
slightly better performance results from this
configuration.
Power-Down Functionality
(Except ICL3232E)
The already low current requirement drops
significantly when the device enters power-down
mode. In power-down, supply current drops to 1µA,
because the on-chip charge pump turns off (V+
collapses to VCC, V- collapses to GND), and the
transmitter outputs three-state. Inverting receiver
outputs may or may not disable in power-down; refer
to Table 2 for details. This micro-power mode makes
these devices ideal for battery powered and portable
applications.
Software Controlled (Manual) Power-Down
Most devices in the ICL32xxE family provide pins that
allow the user to force the IC into the low power,
standby state.
On the ICL3222E and ICL3241E, the power-down
control is via a simple shutdown (SHDN) pin. Driving
this pin high enables normal operation, while driving it
low forces the IC into its power-down state. Connect
SHDN to VCC if the power-down function isn’t needed.
Note that all the receiver outputs remain enabled
during shutdown (see Table 2). For the lowest power
consumption during power-down, the receivers should
also be disabled by driving the EN input high (see next
section, and Figures 2 and 3).
The ICL3221E, ICL3223E, and ICL3243E utilize a two
pin approach where the FORCEON and FORCEOFF
inputs determine the IC’s mode. For always enabled
operation, FORCEON and FORCEOFF are both strapped
high. To switch between active and power-down
modes, under logic or software control, only the
FORCEOFF input need be driven. The FORCEON state
isn’t critical, as FORCEOFF dominates over FORCEON.
Nevertheless, if strictly manual control over powerdown is desired, the user must strap FORCEON high to
disable the automatic power-down circuitry. ICL3243E
inverting (standard) receiver outputs also disable when
the device is in manual power-down, thereby
eliminating the possible current path through a
shutdown peripheral’s input protection diode (see
Figures 2 and 3).

NOTE:
7. Applies only to the ICL3241E and ICL3243E.
The INVALID output always indicates whether or not a
valid RS-232 signal is present at any of the receiver
inputs (see Table 2), giving the user an easy way to
determine when the interface block should power
down. In the case of a disconnected interface cable
where all the receiver inputs are floating (but pulled to
GND by the internal receiver pull down resistors), the
INVALID logic detects the invalid levels and drives the
output low. The power management logic then uses
this indicator to power down the interface block.
Reconnecting the cable restores valid levels at the
receiver inputs, INVALID switches high, and the power
management logic wakes up the interface block.
INVALID can also be used to indicate the DTR or RING
INDICATOR signal, as long as the other receiver inputs
are floating, or driven to GND (as in the case of a
powered down driver). Connecting FORCEOFF and
FORCEON together disables the automatic power-down
feature, enabling them to function as a manual
SHUTDOWN input (see Figure 4).

Even greater power savings is available by using the
devices which feature an automatic power-down
function. When no valid RS-232 voltages (see Figure 6)
are sensed on any receiver input for 30µs, the charge
pump and transmitters power-down, thereby reducing
supply current to 1µA. Invalid receiver levels occur
whenever the driving peripheral’s outputs are shut off
(powered down) or when the RS-232 interface cable is
disconnected. The ICL32xxE powers back up whenever it
detects a valid RS-232 voltage level on any receiver
input. This automatic power-down feature provides
additional system power savings without changes to the
existing operating system.

With any of the control schemes, the time required to
exit power-down, and resume transmission is only
100µs. A mouse, or other application, may need more
time to wake up from shutdown. If automatic
power-down is being utilized, the RS-232 device will
reenter power-down if valid receiver levels aren’t
reestablished within 30µs of the ICL32xxE powering up.
Figure 5 illustrates a circuit that keeps the ICL32xxE from
initiating automatic power-down for 100ms after
powering up. This gives the slow-to-wake peripheral
circuit time to reestablish valid RS-232 output levels.

Automatic power-down operates when the FORCEON
input is low, and the FORCEOFF input is high. Tying
FORCEON high disables automatic power-down, but
manual power-down is always available via the
overriding FORCEOFF input. Table 2 summarizes the
automatic power-down functionality.

Devices with the automatic power-down feature include
an INVALID output signal, which switches low to indicate
that invalid levels have persisted on all of the receiver
inputs for more than 30µs (see Figure 7). INVALID
switches high 1µs after detecting a valid RS-232 level on
a receiver input. INVALID operates in all modes (forced
or automatic power-down, or forced on), so it is also
useful for systems employing manual power-down
circuitry. When automatic power-down is utilized,
INVALID = 0 indicates that the ICL32xxE is in
power-down mode.
The time to recover from automatic power-down mode is
typically 100µs.

Several devices also feature an EN input to control the
receiver outputs. Driving EN high disables all the
inverting (standard) receiver outputs placing them in a
high impedance state. This is useful to eliminate supply
current, due to a receiver output forward biasing the
protection diode, when driving the input of a powered
down (VCC = GND) peripheral (see Figure 2). The enable
input has no effect on transmitter nor monitor (ROUTB)
outputs.
Figure 8 shows the response of two transmitter outputs
when exiting power-down mode. As they activate, the
two transmitter outputs properly go to opposite RS-232
levels, with no glitching, ringing, nor undesirable
transients. Each transmitter is loaded with 3kΩin parallel
with 2500pF. Note that the transmitters enable only
when the magnitude of the supplies exceed
approximately 3V..

Capacitor Selection
The charge pumps require 0.1µF capacitors for 3.3V
operation. For other supply voltages refer to Table 3 for
capacitor values. Do not use values smaller than those
listed in Table 3. Increasing the capacitor values (by a
factor of 2) reduces ripple on the transmitter outputs and
slightly reduces power consumption. C2, C3, and C4 can
be increased without increasing C1’s value, however, do
not increase C1 without also increasing C2, C3, and C4 to
maintain the proper ratios (C1 to the other capacitors).
When using minimum required capacitor values, make
sure that capacitor values do not degrade excessively
with temperature. If in doubt, use capacitors with a

COMPATIBILITY
Compatible with ACT and
HCT CMOS, and with TTL.
ICL32XX outputs are
incompatible with AC, HC,
and CD4000 CMOS inputs.
±15kV ESD Protection
All pins on ICL32XX devices include ESD protection
structures, but the ICL32xxE family incorporates
advanced structures which allow the RS-232 pins
(transmitter outputs and receiver inputs) to survive ESD
events up to ±15kV. The RS-232 pins are particularly
vulnerable to ESD damage because they typically
connect to an exposed port on the exterior of the finished
product. Simply touching the port pins, or connecting a
cable, can cause an ESD event that might destroy
unprotected ICs. These new ESD structures protect the
device whether or not it is powered up, protect without
allowing any latch-up mechanism to activate, and don’t
interfere with RS-232 signals as large as ±25V.
Human Body Model (HBM) Testing
As the name implies, this test method emulates the ESD
event delivered to an IC during human handling. The
tester delivers the charge through a 1.5kΩ current
limiting resistor, making the test less severe than the
IEC61000 test which utilizes a 330Ω limiting resistor. The
HBM method determines an IC’s ability to withstand the
ESD transients typically present during handling and
manufacturing. Due to the random nature of these
events, each pin is tested with respect to all other pins.
The RS-232 pins on “E” family devices can withstand
HBM ESD events to ±15kV.
Typical Performance Curves
IEC61000-4-2 Testing
The IEC61000 test method applies to finished
equipment, rather than to an individual IC. Therefore,
the pins most likely to suffer an ESD event are those that
are exposed to the outside world (the RS-232 pins in this
case), and the IC is tested in its typical application
configuration (power applied) rather than testing each
pin-to-pin combination. The lower current limiting
resistor coupled with the larger charge storage capacitor
yields a test that is much more severe than the HBM test.
The extra ESD protection built into this device’s RS-232
pins allows the design of equipment meeting level 4
criteria without the need for additional board level
protection on the RS-232 port.
AIR-GAP DISCHARGE TEST METHOD
For this test method, a charged probe tip moves toward
the IC pin until the voltage arcs to it. The current
waveform delivered to the IC pin depends on approach
speed, humidity, temperature, etc., so it is difficult to
obtain repeatable results. The “E” device RS-232 pins
withstand ±15kV air-gap discharges.
CONTACT DISCHARGE TEST METHOD
During the contact discharge test, the probe contacts the
tested pin before the probe tip is energized, thereby
eliminating the variables associated with the air-gap
discharge. The result is a more repeatable and
predictable test, but equipment limits prevent testing
devices at voltages higher than ±8kV. All “E” family
devices survive ±8kV contact discharges on the RS-232
pins.
