3 Description
The MAX3232E device consists of two line drivers,
two-line receivers, and a dual charge-pump circuit
with ±15-kV IEC ESD protection pin to pin (serial-port
connection pins, 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.
