TRS3122E 2Tx/2Rx Low Power RS-232 Transceiver

Texas Instruments TRS3122E 2Tx/2Rx Low Power RS-232 Transceiver is a two-driver and two-receiver RS-232 interface device, with split supply pins for mixed-voltage operation. All RS-232 inputs and outputs are protected to ±15kV using the IEC 61000-4-2 Air-Gap Discharge method, ±8kV using the IEC 61000-4-2 Contact Discharge method, and ±15kV using the Human-Body Model. The charge pump requires five small 0.1µF capacitors for operation from as low as a 1.8V supply. The TRS3122E is capable of running at data rates up to 1000kbps, while maintaining RS-232-compatible output levels. Auto Powerdown Plus automatically places the device in a low power mode when the device has not received or transmitted data for more than 30 seconds. This feature makes this device a very attractive option for battery powered or other power-sensitive applications.
