Description
The ST3232E is a 3V powered EIA/TIA-232 and
V.28/V.24 communication interfaces with low
power requirements, high data-rate capabilities
and enhanced electrostatic discharge (ESD)
protection to ±8kV using IEC1000-4-2 Contact
Discharge and ±15kV using the Human Body
Model. ST3232E has a proprietary low dropout
transmitter output stage providing true RS-232
performance from 3 to 5V supplies with a dual
charge pump. The charge pump requires only four

small 0.1µF standard external capacitors for
operations from 3V supply.
The ST3232E has two receivers and two drivers.
The device is guaranteed to run at data rates of
250Kbps while maintaining RS-232 output levels.
Typical applications are Notebook, Subnotebook
and Palmtop Computers, Battery Powered
Equipment, Hand-Held Equipment, Peripherals
and Printers..
