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 VCC and V− is raised toward GND. Receiver outputs also can be placed in the high-impedance state by setting EN high.
