MAX3232ESE

The UMW MAX3232ESE 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.
