Description
The ST3232 is a 3 V powered EIA/TIA-232 and
V.28/V.24 communication interface with low power
requirements, high data-rate capabilities.
ST3232 has a proprietary low dropout transmitter
output stage providing true RS-232 performance
from 3 to 5.5 V supplies. The device requires only
four small 0.1 mF standard external capacitors for
operations from 3 V supply.
The ST3232 has two receivers and two drivers.
The device is guaranteed to run at data rates of
250 kbps while maintaining RS-232 output levels.
Typical applications are Notebook, Subnotebook
and Palmtop Computers, Battery Powered
