description/ordering information
The SN65C3232 and SN75C3232 consist of two line drivers, two line receivers, and a dual charge-pump circuit
with
15-kV ESD protection pin to pin (serial-port connection pins, including GND). These devices provide the
electrical interface between an asynchronous communication controller and the serial-port connector. The
charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. The devices
operate at data signaling rates up to 1 Mbit/s and a driver output slew rate of 24 V/
s to 150 V/
s.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltages are with respect to network GND.
2. Maximum power dissipation is a function of TJ(max),
JA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) - TA)/
JA. Operating at the absolute maximum TJ of 150
C can affect reliability.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
