DE SCRIPTION

The UMW ST3232BDR has 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.
