?15kv Esd Protected 3 To 5.5v, 400kbps, Rs-232 Transceiver With Auto-powerdownThe 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 input are
protected to 8KV 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 serial port.
The ST3241E has a proprietary low-dropout
transmitter output stage enabling true RS-232
performance from a 3.0V to 5.5V supply with a
dual Charge Pump The device is guaranteed to
run at data rates of 250kbps while maintaining
RS-232 output levels.
It is a complete serial port (3 drivers, 5 receivers)
intended for notebook or subnotebook computers.
Receivers R1 and R2 have extra outputs in
addition to their standard outputs. These extra
output are always active.
Typical application are in notebook, subnotebook,
palmtop computers, battery-powered equipment,
hand-held equipment, peripherals and printers. By STMicroelectronics
