General 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 0.1mF standard external capacitors
for operating from 3V supply. The ST3222 has two receivers and two drivers. The
ST3222 features a 1mA 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 1mA supply
current. The device is guaranteed to run at data rates of 250Kbps while maintaining RS-
232 output levels.
