The TRS3253E device is a three-driver and five-receiver 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 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 capacitors for operation from a single 3.3-V or 5-V supply. The TRS3253E is capable of running at data rates up to 1000 kbps, while maintaining RS-232 compliant output levels.

The TRS3253E is available in a space-saving VQFN package (4-mm × 4-mm RSM).

Auto-powerdown-plus automatically powers down drivers to reduce power after 30 seconds of inactivity. In powerdown state supply current is 10 µA maximum.

Receiver input voltage status is available on INVALID logic output even when the device is in powerdown state.
