TRS3232 Datasheet 3-v To 5.5-v Multichannel Rs-232 Line Driver/receiver

Manufacturer: Texas Instruments

Overview: TRS3232 SLLS812B – JULY 2007 – REVISED JUNE 2021 TRS3232 3-V to 5.

General Description

The TRS3232 consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection terminal-to-terminal (serialport connection terminals, including GND).

The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector.

The charge pump and four small external capacitors allow operation from one 3-V to 5.5-V supply.
