Features
Description
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 ±15 kV 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 3.0 V to 5.5 V supply with a
dual charge pump. The device is guaranteed to
run at data rates of 250 kbps while maintaining
RS-232 output levels.
