DESCRIPTION
The SP202E/232E/233E/310E/312E devices are a family of line driver and receiver pairs that
meet the specifications of RS-232 and V.28 serial protocols with enhanced ESD performance.
The ESD tolerance has been improved on these devices to over ±15KV for both Human Body
Model and IEC1000-4-2 Air Discharge Method. These devices are pin-to-pin compatible with
Sipex's SP232A/233A/310A/312A devices as well as popular industry standards. As with the
initial versions, the SP202E/232E/233E/310E/312E 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.

Figure 2. Typical Circuits using the SP233ECP and SP233ECT
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-D
2.1.7, Paragraph (5)]. However, the transition re-
gion slew rate of these enhanced products is typi-
cally 10V/µs. The smooth transition of the loaded
output from VOL to VOH clearly meets the mono-
tonicity requirements of the standard [EIA
RS-232-D 2.1.7, Paragraphs (1) & (2)].
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
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 pro-
tected against voltages up to ±15V. Should an
input be left unconnected, a 5KOhm pulldown
resistor to ground will commit the output of the
receiver to a high state.
