3 Description
The TRS3253E device is a three-driver and fivereceiver RS-232 interface device, with split supply pins for mixed-signal operations without needing an external voltage translator. All RS-232 inputs and outputs are protected to ±15 k V using the IEC 610004-2 Air-Gap Discharge method, ±8 k V using the IEC 61000-4-2 Contact Discharge method, and ±15 k V using the Human Body Model.
The charge pump requires only four capacitors for operation from a single 3.3-V or 5-V supply. The TRS3253E is capable...
