DESCRIPTION
The ST3222E is a 3V 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 ±8kV using IEC1000-4-2 Contact
Discharge and ±15kV using the Human Body
Model. ST3222E has a proprietary low dropout
transmitter output stage providing true RS-232
performance from 3 to 5V supplies with a dual
charge pump. The charge pump requires only four
small 0.1mF external capacitors for operation form
3V supply.
The device has two receivers and two drivers. The
ST3222E features a 1 A shutdown mode that
reduces power consumption and extends battery
life in portable systems. Its receivers can remain
active in shutdown mode, allowing external
