3 Description

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.
