TRS3238IPWR

Drivers, Receivers, Transceivers Overview

The TRS3238IPWR is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates on a single power supply ranging from 3 V to 5.5 V and features integrated charge pumps for generating the required voltages. The device provides five drivers and three receivers, supporting data rates up to 250 kbps. It includes +/-15-kV electrostatic discharge (ESD) protection on all lines according to the Human Body Model (HBM). The component is housed in a 28-pin TSSOP package and is rated for an operating temperature range of -40°C to +85°C.
