TRSF3232EIDBR

TRSF3232EIDBR Description

The TRSF3232EIDBR from Texas Instruments is a high-performance, full-duplex RS-232 transceiver designed for robust serial communication in industrial and embedded systems. Housed in a compact 16-SSOP package, this surface-mount IC integrates 2 drivers and 2 receivers, supporting data rates up to 1 Mbps. Operating across a 3V to 5.5V supply range, it ensures compatibility with both 3.3V and 5V logic systems. Despite its obsolete status, it remains a reliable choice for legacy designs, offering 300 mV receiver hysteresis for enhanced noise immunity in electrically noisy environments. Compliant with ROHS3 and REACH standards, it is suitable for global applications.
