UNISONIC TECHNOLOGIES CO., LTD

UT3222

CMOS IC

3.0V TO 5.5V LOW POWER

MULTICHANNEL RS-232 LINE

TRANSCEIVERS USING FOR

0.1μF EXTERNAL CAPACITORS



DESCRIPTION

The UTC UT3222 have two receivers and two drivers, and a dual

charge-pump circuit. 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 3.0V to 5.5V supply. The device operates at data

signaling rates up to 250kbit/s and a maximum of 35V/μs driver output

slew rate.

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.


