TRSF3221ECPW Description

Short technical summary and product information.

The TRSF3221ECPW from Texas Instruments is a single-channel RS-232 line driver and receiver designed for efficient serial communication. It operates with a VCC supply ranging from 3V to 5.5V and supports data signaling rates up to 1Mbit/s.

 

Key features include ±15kV IEC ESD protection on RS-232 pins, protecting against electrostatic discharge. The device also incorporates an auto-powerdown feature that automatically disables drivers when the serial port is inactive, reducing power consumption to a typical standby current of 1μA. It accepts 5V logic input with a 3.3V supply.

 

This transceiver is available in a compact 16-TSSOP package, suitable for surface mount applications. The TRSF3221ECPW is ideal for various applications including industrial PCs, wired networking, data centers, and battery-powered systems where reliable serial communication and power efficiency are crucial.

 

External capacitors, specifically 4 × 0.1μF, are required for operation. The device provides flexible power management options and an INVALID output to indicate the presence of a valid RS-232 signal.
