ST3243CPR

ST3243CPR is a ±15KV ESD protected 3 to 5.5V, 400Kbps, RS-232 transceiver with auto-power-down. This device consists of 3 drivers, 5 receivers and a dual charge pump circuit. The devices meet the requirements of EIA/TIA and V.28/V.24 communication standards providing high data rate capability and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±8kV using IEC61000-4-2 contact discharge and ±15KV IEC61000-4-2 air discharge. The receiver R2 is always active to implement a wake-up feature for the serial port. This device has a proprietary low-dropout transmitter output stage enabling true RS-232 performance from a 3V to 5.5V supply with a dual charge pump. This device is guaranteed to run at data rates of 250Kbps while maintaining RS-232 output levels.
