SN65C3232E Datasheet 3-v To 5.5-v Two-channel Rs-232 1-mbit/s Line Drivers/receivers

Manufacturer: Texas Instruments

Overview: SN65C3232E, SN75C3232E SLLS697B – DECEMBER 2005 – REVISED JUNE 2021 SNx5C3232E 3-V To 5.

General Description

The SN65C3232E and SN75C3232E consist of two line drivers, two line receivers, and a dual chargepump 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.
