MAX3232ID

The MAX3232 device consists of two line drivers,
two line receivers, and a dual charge-pump circuit
with ±15-kV ESD protection terminal to terminal
(serial-port connection terminals, including GND).
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-V
to 5.5-V supply. The devices operate at data signaling
rates up to 250 kbit/s and a maximum of 30-V/μs
driver output slew rate
