TRS3253EIRSMR

The TRS3253EIRSMR is a RS-232 Transceiver with split supply pin for logic side. 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 input and output is protected to ±8kV using the IEC 61000-4-2 air-gap discharge method, ±8kV using the IEC 61000-4-2 contact discharge method and ±15kV using the human body model. The charge pump requires only four capacitors for operation from a single 3.3 or 5V supply. It is capable of running at data rate up to 1000kbps, while maintaining RS-232 compliant output levels. Auto-power-down-plus automatically powers down drivers to reduce power after 30 seconds of inactivity. In power-down state supply current is 10µA maximum.
