UNISONIC TECHNOLOGIES CO., LTD UT3222 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.
