TRS3232E Datasheet 3-v To 5.5-v Multichannel Rs-232 Line Driver/receiver

Manufacturer: Texas Instruments

Overview: TRS3232E SLLS790D – JUNE 2007 – REVISED JUNE 2021 TRS3232E 3-V to 5.

General Description

The TRS3232E device consists of two line drivers, two-line receivers, and a dual charge-pump circuit with ±15-kV IEC ESD protection pin to pin (serial-port connection pins, including GND).

The device meets the requirements of TIA/EIA-232F 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 a single 3-V to 5.5-V supply.
