TRSF3221IPWR TI RS-232 Transceiver | 16-TSSOP | 3V-5.5V, 250kbps

Product Overview

The TRSF3221IPWR from Texas Instruments is a single-channel RS-232 line driver/receiver designed for serial communication in industrial and consumer applications. It operates from a single 3V to 5.5V supply, featuring a proprietary low-dropout output stage that delivers true RS-232 performance. 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-pin TSSOP package, it is ideal for space-constrained designs.
