TRS222CDWR Description

Short technical summary and product information.

The Texas Instruments TRS222CDWR is a 5-V dual RS-232 transceiver IC, suitable for applications requiring robust serial communication interfaces. This device meets or exceeds TIA/EIA-232-F and ITU v.28 standards, providing an electrical interface between asynchronous communication controllers and serial port connectors.

 

Key features include ±15kV ESD protection for RS-232 bus pins, ensuring device reliability. It operates from a single 5V supply and supports data signaling rates up to 200 kbit/s. The transceiver also includes a shutdown mode that reduces supply current to a typical 2 µA.

 

Packaged in an 18-SOIC (0.295", 7.50mm Width) surface-mount package, the TRS222CDWR is designed for ease of integration into various electronic systems. It requires four external 0.1µF capacitors for operation. The device also exhibits latch-up performance exceeding 100mA per JESD 78, Class II.

 

Applications for this transceiver include battery-powered systems, PDAs, notebooks, laptops, palmtop PCs, and other hand-held equipment where efficient and protected serial communication is essential.
