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
μ
A 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
μ
A supply current.
The device is guaranteed to run at data rates of
250Kbps while maintaining RS-232 output levels.
Typical applications are Notebook, Subnotebook
and
Palmtop
Computers,
Equipment, Hand-Held Equipment, Peripherals
and Printers.
