Description
The ST3232E is a 3 V 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 ± 8 kV using IEC1000-4-2 Contact
Discharge and ± 15 kV using the Human Body
Model. ST3232E has a proprietary low dropout
transmitter output stage providing true RS-232
performance from 3 to 5 V supplies with a dual
charge pump. The charge pump requires only
four small 0.1 µF standard external capacitors for
operations from 3 V supply.
The ST3232E has two receivers and two drivers.
The device is guaranteed to run at data rates of
250 kbps while maintaining RS-232 output levels.
