UNISONIC TECHNOLOGIES CO., LTD

UT3222

Preliminary

CMOS IC

3V TO 5.5V MULTICHANNEL

RS-232 LINE TRANSCEIVERS

WITH ±15kV ESD PROTECTION



DESCRIPTION

The UTC UT3222 have two receivers and two transmitters, and a

dual charge-pump circuit with ±15kV ESD protection pin to pin

(serial-port connection pins, including GND). The device meets the

requirements of TIA/EIA-232-F and provides the electrical interface

between an asynchronous communication controller and the

serial-port connector. The charge pump and four small external

capacitors allow operation from a single 3V to 5.5V supply. The

device operates at data signaling rates up to 250 kbit/s and a

maximum of 30V/μS driver output slew rate.

TSSOP-20

The UTC UT3222 can be placed in the power-down mode by

setting PWRDOWN low, which draws only 1μA from the power

supply. When the device is powered down, the receivers remain

active while the drivers are placed in the high-impedance state. Also,

during power down, the onboard charge pump is disabled; V+ is

lowered to V_CCand V− is raised toward GND. Receiver outputs also

can be placed in the high-impedance state by setting EN high.
