DESCRIPTION
The ST3222isa 3V powered EIA/TIA-232 and
V.28/V.24 communications interface with low
power requirements and high data-rate
capabilities. ST3222 hasa proprietary low dropout
transmitter output stage providing true RS-232
performance from3to 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.
TheST3222featuresa 1μA shutdown mode that
reduces power consumption and extends battery
lifein portable systems. Its receivers can remain
active in shutdown mode, allowing external
devices such as modemsto be monitored using
only 1μA supply current.
The deviceis guaranteedto runat data ratesof
250Kbps while maintaining RS-232 output levels.
Typical applications are Notebook, Subnotebook
and Palmtop Computers, Battery Powered
Equipment, Hand-Held Equipment, Peripherals
and Printers.
