ST202BDR

Drivers, Receivers, Transceivers Overview

The ST202BDR is a dual-driver, dual-receiver RS-232 transceiver manufactured by STMicroelectronics. It operates from a single 5 V power supply (4.5 V to 5.5 V) and requires only four external 0.1 µF capacitors. The device supports data rates up to 400 kbps with a typical transition slew rate of 12 V/µs. It functions within an industrial temperature range of -40 °C to +85 °C. The IC features a typical no-load supply current of 1.5 mA and provides transmitter output voltage swings of ±9 V. It is housed in a 16-pin SOIC package.
