DE SCRIPTION

The UMW MAX3232CDR 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.
