DESCRIPTION
The SP232A/233A/310A/312A devices are a family of line driver and receiver pairs that meet the
specifications of RS-232 and V.28 serial protocols. These devices are pin-to-pin compatible with
popular industry standards. As with the initial versions, the SP232A/233A/310A/312A devices
feature at least 120Kbps data rate under load, 0.1µF charge pump capacitors, and overall
ruggedness for commercial applications. This family also features Sipex's BiCMOS design
allowing low power operation without sacrificing performance. The series is available in plastic
DIP and SOIC packages operating over the commercial and industrial temperature ranges.

FEATURES…
The SP232A/233A/310A/312A devices are a
family of line driver and receiver pairs that meet
the specifications of RS-232 and V.28 serial
protocols. The ESD tolerance has been improved on these devices to over ±2KV for the
Human Body Model. These devices are pin-topin compatible with popular industry standards.
The SP232A/233A/310A/312A devices
feature10V/µs slew rate, 120Kbps data rate under load, 0.1µF charge pump capacitors, overall
ruggedness for commercial applications, and
increased drive current for longer and more
flexible cable configurations. This family also
features Sipex's BiCMOS design allowing low
power operation without sacrificing performance.
The SP310A provides identical features as the
SP232A with the addition of a single control
line which simultaneously shuts down the internal DC/DC converter and puts all transmitter
and receiver outputs into a high impedance
state. The SP312A is identical to the SP310A
with separate tri-state and shutdown control
lines.
THEORY OF OPERATION
The SP232A, SP233A, SP310A and SP312A
devices are made up of three basic circuit blocks –
1) a driver/transmitter, 2) a receiver and 3) a charge
pump. Each block is described below.
Driver/Transmitter
The drivers are inverting transmitters, which accept TTL or CMOS inputs and output the RS-232
signals with an inverted sense relative to the input
logic levels. Typically the RS-232output voltage
swing is ±6V. Even under worst case loading
conditions of 3kOhms and 2500pF, the output is
guaranteed to be ±5V, which is consistent with the
RS-232 standard specifications. The transmitter
outputs are protected against infinite short-circuits
to ground without degradation in reliability.
The SP232A/233A/310A/312A devices have
internal charge pump voltage converters which
allow them to operate from a single +5V supply.
The charge pumps will operate with polarized or
non-polarized capacitors ranging from 0.1 to 1µF
and will generate the ±6V needed for the RS232 output levels. Both meet all EIA RS-232F
and ITU V.28 specifications.

Figure 2. Typical Circuits using the SP233ACP and SP233ACT
The instantaneous slew rate of the transmitter
output is internally limited to a maximum of 30V/
µs in order to meet the standards [EIA RS-232-F ].
The transition region slew rate of these enhanced
products is typically 10V/µs. The smooth transition of the loaded output from VOL to VOH clearly
meets the monotonicity requirements of the standard [EIA RS-232-F].
inputs have a typical hysteresis margin of 500mV.
This ensures that the receiver is virtually immune
to noisy transmission lines.
The input thresholds are 0.8V minimum and 2.4V
maximum, again well within the ±3V RS-232
requirements. The receiver inputs are also protected against voltages up to ±25V. Should an
input be left unconnected, a 5KΩ pulldown resistor to ground will commit the output of the receiver
to a high state.
Receivers
The receivers convert RS-232 input signals to
inverted TTL signals. Since the input is usually
from a transmission line, where long cable lengths
and system interference can degrade the signal, the

Figure 4. Charge Pump — Phase 1
In actual system applications, it is quite possible
for signals to be applied to the receiver inputs
before power is applied to the receiver circuitry.
This occurs, for example, when a PC user attempts
to print, only to realize the printer wasn’t turned on.
In this case an RS-232 signal from the PC will
appear on the receiver input at the printer. When
the printer power is turned on, the receiver will
operate normally. All of these enhanced devices
are fully protected.
Phase 2
— VSS transfer — Phase two of the clock connects the negative terminal of C2 to the VSS
storage capacitor and the positive terminal of C2
to ground, and transfers the generated –l0V to
C3. Simultaneously, the positive side of capacitor C 1 is switched to +5V and the negative side
is connected to ground.
Phase 3
— VDD charge storage — The third phase of the
clock is identical to the first phase — the charge
transferred in C1 produces –5V in the negative
terminal of C1, which is applied to the negative
side of capacitor C2. Since C2+ is at +5V, the
voltage potential across C2 is a maximum of l0V.
Charge Pump
The charge pump is a Sipex–patented design
(5,306,954) and uses a unique approach compared to older less–efficient designs. The charge
pump still requires four external capacitors, but
uses a four–phase voltage shifting technique to
attain symmetrical power supplies. There is a
free–running oscillator that controls the four
phases of the voltage shifting. A description of
each phase follows.
Phase 4
— VDD transfer — The fourth phase of the clock
connects the negative terminal of C2 to ground,
and transfers the generated l0V across C2 to C4,
the VDD storage capacitor. Again, simultaneously
with this, the positive side of capacitor C1 is
switched to +5V and the negative side is connected to ground, and the cycle begins again.
Phase 1
— VSS charge storage —During this phase of
the clock cycle, the positive side of capacitors
C1 and C2 are initially charged to +5V. Cl+ is
then switched to ground and the charge in C1– is
transferred to C2–. Since C2+ is connected to
+5V, the voltage potential across capacitor C2 is
now 10V.
Since both V+ and V– are separately generated
from VCC; in a no–load condition V+ and V– will
be symmetrical. Older charge pump approaches
VCC = +5V

Shutdown (SD) and Enable (EN) for the
SP310A and SP312A
Both the SP310A and SP312A have a shutdown/
standby mode to conserve power in battery-powered systems. To activate the shutdown mode,
which stops the operation of the charge pump, a
logic “0” is applied to the appropriate control line.
For the SP310A, this control line is ON/OFF (pin
18). Activating the shutdown mode also puts the
that generate V– from V+ will show a decrease in
the magnitude of V– compared to V+ due to the
inherent inefficiencies in the design.
The clock rate for the charge pump typically
operates at greater than 15kHz. The external
capacitors can be as low as 0.1µF with a 10V
breakdown voltage rating.

Pin Strapping for the SP233ACT/ACP
The SP233A packaged in the 20–pin SOIC package (SP233ACT) has a slightly different pinout
than the SP233A in PDIP packaging (SP233ACP).
To operate properly, the following pairs of pins
must be externally wired together:
SP310A transmitter and receiver outputs in a high
impedance condition (tri-stated). The shutdown
mode is controlled on the SP312A by a logic “0”
on the SHUTDOWN control line (pin 18); this also
puts the transmitter outputs in a tri–state mode.
The receiver outputs can be tri–stated separately
during normal operation or shutdown by a logic
“1” on the ENABLE line (pin 1).
Pins Wired
Together
Wake–Up Feature for the SP312A
The SP312A has a wake–up feature that keeps
all the receivers in an enabled state when the
device is in the shutdown mode. Table 1 defines
the truth table for the wake–up function.
Two V- Pins
Two C2+ Pins
Two C2- Pins
With only the receivers activated, the SP312A
typically draws less than 5µA supply current.
In the case of a modem interfaced to a computer
in power down mode, the Ring Indicator (RI)
signal from the modem would be used to "wake
up" the computer, allowing it to accept data
transmission.

Connect Pins 6 and 9
to GND
After the ring indicator signal has propagated
through the SP312A receiver, it can be used to
trigger the power management circuitry of the
computer to power up the microprocessor, and
bring the SD pin of the SP312A to a logic high,
taking it out of the shutdown mode. The receiver
propagation delay is typically 1µs. The enable
time for V+ and V– is typically 2ms. After V+ and
V– have settled to their final values, a signal can
be sent back to the modem on the data terminal
ready (DTR) pin signifying that the computer is
ready to accept and transmit data.
