                  UT3232 Datasheet

                  3.0V TO 5.5V LOW POWER MULTICHANNEL RS-232 LINE

                  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.
                  * Exceeds ±8KV ESD Protection(HBM) for RS-232 I/O Pins
                  * Meets the Requirements of TIA/EIA-232-F and ITU V.28 Standards
                  * Operates With 3.0V to 5.5V VCC Supply
                  * Operates Up To 250kbit/s Data Rate
                  * Two Drivers and Two Receivers
                  * External Capacitors 4×0.1μF
                  * Accepts 5.0V Logic Input With 3.3V Supply
