The TRSF3221ECDBR from Texas Instruments is a single-channel RS-232 line driver and receiver. It is designed to provide the electrical interface between an asynchronous communication controller and a serial port connector.
This transceiver operates with a VCC supply ranging from 3V to 5.5V and supports data signaling rates up to 1Mbps. It features robust ESD protection for RS-232 pins, exceeding ±15kV using the Human-body model (HBM) and ±15kV via IEC 61000-4-2 air-gap discharge.
Key features include a low standby current of 1μA typical and an auto-powerdown function that automatically disables drivers for power savings when the serial port is inactive. It requires four external capacitors of 0.1μF and can accept 5V logic input with a 3.3V supply.
The TRSF3221ECDBR is available in a 16-SSOP package, suitable for surface mount applications. Its operating temperature range is from 0°C to 70°C.
