TRS3122ERGET

TRS3122ERGET Description
The TRS3122E is a two-driver and two-receiver RS232 interface device, with split supply pins for mixe-dvoltage 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- μFcapacitors 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-232compatible output levels.
The TRS3122E has a unique VL pin that allows operation in mixed-logic voltage systems. Both driverin (DIN) and receiver out (ROUT) logic levels are pin programmable through the VL pin. This eliminates theneed foradditional voltage level shifterwhileinterfacingwith low-voltage microcontrollersorUARTs. Auto Powerdown Plus automatically places 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 powersensitive applications. TRS3122ERGET
