The TRS3122E 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 ±15 kV using the IEC 61000-4-2 Air-Gap Discharge method, ±8 kV using the IEC 61000-4-2 Contact Discharge method, and ±15 kV using the Human-Body Model.
●The charge pump requires five small 0.1-µF capacitors for operation from as low as a 1.8-V supply. The TRS3122E is capable of running at data rates up to 1000 kbps, while maintaining RS-232-compatible output levels.
●The TRS3122E has a unique VL pin that allows operation in mixed-logic voltage systems. Both driver in (DIN) and receiver out (ROUT) logic levels are pin programmable through the VL pin. This eliminates the need for additional voltage level shifter while interfacing with low-voltage microcontrollers or UARTs.
●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.
