SN75C3221PW TI RS-232 Transceiver | 16-TSSOP | 3V-5.5V, 1Mbps

Product Overview

The SN75C3221PW from Texas Instruments is a single-channel RS-232 line driver/receiver designed for serial communication in portable and space-constrained applications. Operating from a single 3V to 5.5V supply, it features a proprietary low-dropout output stage delivering true RS-232 performance with a data rate up to 1 Mbps. The device integrates a charge pump for on-chip generation of ±5.5V RS-232 voltage levels, eliminating the need for multiple power supplies. Housed in a compact 16-TSSOP package, it is ideal for battery-powered systems, industrial control, and telecom infrastructure.
