3.0V TO 5.5V LOW POWER

MULTICHANNEL RS-232 LINE

TRANSCEIVERS USING FOR

0.1μF EXTERNAL CAPACITORS



DESCRIPTION

The UTC UT3232 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.
