Features
Description
The ST3222E is a 3 V powered EIA/TIA-232 and
V.28/V.24 communications interface 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. ST3222E 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 mF external capacitors for operation
form 3 V supply. The device has two receivers and
two drivers. The ST3222E features a 1 mA
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 1 mA supply current. The
device is guaranteed to run at data rates of 250
Kbps while maintaining RS-232 output levels.
