TRS202CDWRG4

Drivers, Receivers, Transceivers Overview

The TRS202CDWRG4 is a dual RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 5-V supply using an internal charge pump circuit requiring four external 0.1-μF capacitors. The device supports data signaling rates up to 120 kbit/s with a maximum driver output slew rate of 30 V/μs. It features ±15-kV electrostatic discharge (ESD) protection on the RS-232 bus pins, meeting TIA/EIA-232-F and ITU v.28 standards. The component is housed in a 16-pin SOIC (DW) package and operates within a temperature range of 0°C to 70°C.
