ST3241EBPR

ST3241EBPR is a ±15KV ESD protected 3 to 5.5V, 400Kbps, RS-232 transceiver with auto power-down. The ST3241E device consists of 3 drivers, 5 receivers, and a dual charge-pump circuit. The device meets 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 ±8 kV using IEC 1000-4-2 contact discharge and ±15KV using the human body model. The receiver R2 is always active to implement a wake-up feature for the serial port. It is a complete serial port (3 drivers, 5 receivers) intended for notebook or sub-notebook computers. Receivers R1 and R2 have extra outputs in addition to their standard outputs. These extra outputs are always active. Typical applications are in notebooks, subnotebooks, palmtop computers, battery-powered equipment, hand-held equipment, peripherals, and printers.
