General Description

The TRS3253E is a three-driver and five-receiver RS-232 interface device, with split supply pins for mixed-signal operations.

All RS-232 inputs and outputs are protected to ±8 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 only four small 0.1-μF capacitors for operation from a 3.3-V supply.
