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 ±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 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.
