TRSF3221EIDBR Description

Short technical summary and product information.

The TRSF3221EIDBR 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 VCC supply 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, offering compatibility with various logic levels.

 

This transceiver is available in a 16-pin SSOP package, suitable for surface mounting. It requires four 0.1µF external capacitors for operation. The TRSF3221EIDBR is well-suited for applications such as industrial PCs, wired networking, data centers, and battery-powered systems where reliable serial communication and power efficiency are critical.

 

Applications include industrial PCs, wired networking, data center and enterprise computing, battery-powered systems, PDAs, notebooks, laptops, palmtop PCs, and hand-held equipment.
