The TRSF3221ECPWR from Texas Instruments is a single-channel RS-232 line driver and receiver designed for efficient serial communication. It operates from a flexible 3V to 5.5V supply voltage and supports data signaling rates up to 1Mbit/s.
This transceiver features robust ±15kV IEC ESD protection on its RS-232 pins, safeguarding against electrostatic discharge. It includes an auto-powerdown feature that automatically disables drivers when the serial port is inactive, reducing power consumption to a typical standby current of 1μA. The device accepts 5V logic input when operating with a 3.3V supply.
Packaged in a compact 16-TSSOP, the TRSF3221ECPWR is suitable for surface mount applications. It requires four external 0.1μF capacitors for its charge-pump circuit. The device provides a full duplex interface, with one driver and one receiver, making it ideal for various industrial and computing applications requiring reliable serial data transmission.
