Maxim MAX204EPE 5v, rs-232 transceivers with 0.1î¼f external capacitor Datasheet

19-0065; Rev 7; 12/05
+5V, RS-232 Transceivers
with 0.1µF External Capacitors
Next-Generation Device Features
The MAX200–MAX209/MAX211/MAX213 transceivers
are designed for RS-232 and V.28 communication interfaces where Q12V supplies are not available. On-board
charge pumps convert the +5V input to the Q10V needed
for RS-232 output levels. The MAX201 and MAX209
operate from +5V and +12V, respectively, and contain a
+12V to -12V charge-pump voltage converter.
S For Low-Cost Applications:
MAX221E: ±15kV ESD-Protected, +5V, 1µA,
Single RS-232 Transceiver with AutoShutdown™
S For Low-Voltage and Space-Constrained Applications:
MAX3222E/MAX3232E/MAX3237E/MAX3241E/
MAX3246E: ±15kV ESD-Protected, Down
to 10nA, +3.0V to +5.5V, Up to 1Mbps, True
RS-232 Transceivers (MAX3246E Available in
UCSP™ Package)
The MAX200–MAX209/MAX211/MAX213 drivers and
receivers meet all EIA/TIA-232E and CCITT V.28 specifications at a 20kbps data rate. The drivers maintain the
Q5V EIA/TIA-232E output signal levels at data rates in
excess of 120kbps when loaded in accordance with the
EIA/TIA-232E specification.
S For Space-Constrained Applications:
MAX3228E/MAX3229E: ±15kV ESD-Protected,
+2.5V to +5.5V, RS-232 Transceivers in UCSP
S For Low-Voltage or Data Cable Applications:
MAX3380E/MAX3381E: +2.35V to +5.5V, 1µA,
The 5FW shutdown mode of the MAX200, MAX205,
MAX206, and MAX211 conserves energy in battery-powered systems. The MAX213 has an active-low shutdown
and an active-high receiver enable control. Two receivers of the MAX213 are active, allowing the ring indicator
(RI) to be monitored easily using only 75FW power.
2Tx/2Rx RS-232 Transceivers with ±15kV ESDProtected I/O and Logic Pins
S For Low-Power Applications:
MAX3224E–MAX3227E/MAX3244E/MAX3245E:
±15kV ESD-Protected, 1µA, 1Mbps,
+3.0V to +5.5V, RS-232 Transceivers with
AutoShutdown Plus™
The MAX211 and MAX213 are available in a 28-pin, wide
small-outline (SO) package and a 28-pin shrink smalloutline (SSOP) package, which occupies only 40% of the
area of the SO. The MAX207 is now available in a 24-pin
SO package and a 24-pin SSOP. The MAX203 and
MAX205 use no external components and are recommended for applications with limited circuit board space.

The MAX201 and MAX209 include only the V+ to Vcharge pump, and are intended for applications that
have a VCC = +5V supply and a V+ supply in the +9V to
+13.2V range.
In shutdown mode, V+ is internally connected to VCC by
a 1kI pulldown resistor and V- is internally connected to
ground by a 1kI pullup resistor.

OUTPUT
CL = 150pF
The +5V to Q10V conversion is performed by two
charge-pump voltage converters (Figure 4). The first
uses capacitor C1 to double +5V to +10V, storing +10V
on the V+ output filter capacitor, C3. The second chargepump voltage converter uses capacitor C2 to invert +10V
to -10V, storing -10V on the V- output filter capacitor, C4.
+ 2.5V
When VCC = +5V, the typical driver output-voltage swing
is Q8V when loaded with a nominal 5kI RS-232 receiver.
The output swing is guaranteed to meet the EIA/TIA-232E
and V.28 specifications, which call for Q5V minimum output levels under worst-case conditions. These include
a minimum 3kI load, VCC = +4.5V, and the maximum
operating temperature. The open-circuit output-voltage
swing ranges from (V+ - 0.6V) to V-.
Input thresholds are both CMOS and TTL compatible.
The inputs of unused drivers can be left unconnected
since 400kI pullup resistors to VCC are included onchip. Since all drivers invert, the pullup resistors force
the outputs of unused drivers low. The input pullup resistors typically source 15µA; therefore, the driver inputs
should be driven high or open circuited to minimize
power-supply current in shutdown mode.
When in low-power shutdown mode, the driver outputs
are turned off and their leakage current is less than 1mA,
even if the transmitter output is backdriven between 0V
and (VCC + 6V). Below -0.5V, the transmitter output is
diode clamped to ground with a 1kI series impedance.
The transmitter output is also zener clamped to approximately (VCC + 6V), with a 1kI series impedance.
NOTE: POLARITY OF EN IS REVERSED FOR THE MAX213.

RS-232 Receivers
The receivers convert RS-232 signals to CMOS logic
output levels. Receiver outputs are inverting, maintaining compatibility with driver outputs. The guaranteed
receiver input thresholds of +0.8V and +2.4V are significantly tighter than the Q3.0V threshold required by the
EIA/TIA-232E specification. This allows receiver inputs
to respond to TTL/CMOS logic levels and improves noise
margin for RS-232 levels.
6
The MAX200–MAX209/MAX211/MAX213 guaranteed
+0.8V threshold (+0.6V in shutdown for the MAX213)
ensures that receivers shorted to ground have a logic 1
output. Also, the 5kI input resistance to ground ensures
that a receiver with its input left open also has a logic 1
output.
Receiver inputs have approximately +0.5V hysteresis.
This provides clean output transitions, even with slow
rise and fall time input signals with moderate amounts of
noise and ringing. In shutdown, the MAX213 receivers
R4 and R5 have no hysteresis.
+5V, RS-232 Transceivers
with 0.1µF External Capacitors
All receivers except R4 and R5 on the MAX213 are put
into a high-impedance state in shutdown mode. The
MAX213’s R4 and R5 receivers still function in shutdown
mode. These two receivers are useful for monitoring
external activity while maintaining minimal power consumption.
TWO TRANSMITTER
OUTPUTS:
ONE HIGH, ONE LOW
The enable control is used to put the receiver outputs
into a high-impedance state, so that the receivers can be
connected directly to a three-state bus. It has no effect
on the RS-232 drivers or on the charge pumps.

*SHUTDOWN POLARITY REVERSED FOR MAX213.
MAX213 Receiver Operation in Shutdown
During normal operation, the MAX213’s receiver propagation delay is typically 1Fs. When entering shutdown
with receivers active, R4 and R5 are not valid until 80Fs
after SHDN is driven low. In shutdown mode, propagation delays increase to 4Fs for a high-to-low or a low-tohigh transition.
Figure 5. Transmitter Outputs When Exiting Shutdown
Shutdown and Enable Control
In shutdown mode, the MAX200/MAX205/MAX206/
MAX211/MAX213 charge pumps are turned off, V+ is
pulled down to VCC, V- is pulled to ground, and the
transmitter outputs are disabled. This reduces supply
When exiting shutdown, all receiver outputs are invalid
until the charge pumps reach nominal values (< 2ms
when using 0.1FF capacitors).

Applications Information
Capacitor Selection
The type of capacitor used is not critical for proper
operation. Ceramic capacitors are suggested. To ensure
proper RS-232 signal levels over temperature when
using 0.1FF capacitors, make sure the capacitance
value does not degrade excessively as the temperature
varies. If in doubt, use capacitors with a larger nominal
value. Also observe the capacitors’ ESR value over temperature, since it influences the amount of ripple on V+
and V-. To reduce the output impedance at V+ and V-,
use larger capacitors (up to 10FF). If polarized capacitors are used, obey the polarities shown in Figure 1 and
the pin configurations.
Driver Outputs When Exiting Shutdown
Figure 5 shows two driver outputs exiting shutdown. As
they become active, the two driver outputs go to opposite RS-232 levels (one driver input is high, the other
is low). Each driver is loaded with 3kI in parallel with
2500pF. The driver outputs display no ringing or undesirable transients as they come out of shutdown.
Power-Supply Decoupling
In applications that are sensitive to power-supply noise,
decouple VCC to ground with a capacitor of the same
value as the charge-pump capacitors.
V+ and V- as Power Supplies
A small amount of power can be drawn from V+ and V-,
although this reduces noise margins.
Driving Multiple Receivers
Each transmitter is designed to drive a single receiver.
Transmitters can be paralleled to drive multiple receivers.
Power Supplies for MAX201/MAX209
If at power-up the V+ supply rises after the VCC supply,
place a diode (e.g., 1N914) in series with the V+ supply.
