DESCRIPTION
The ST3222 is a 3V powered EIA/TIA-232 and
V.28/V.24 communications interface with low
power requirements and high data-rate
capabilities. ST3222 has a proprietary low dropout
transmitter output stage providing true RS-232
performance from 3 to 3.6V power supplies. The
device requires only four small 0.1µF standard
external capacitors for operating from 3V supply.
The ST3222 has two receivers and two drivers.
The ST3222 features a 1µA shutdown mode that
reduces power consumption and extends battery
life in portable systems. Its receivers can remain
active in shutdown mode, allowing external
devices such as modems to be monitored using
only 1µA supply current.
The device is guaranteed to run at data rates of
250Kbps while maintaining RS-232 output levels.
