MAX3232
3 V TO 5.5 V MULTICHANNEL RS 232 LINE DRIVER/RECEIVER
WITH
±15
kV ESD PROTECTION
description/ordering information (continued)
The MAX3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with
±15-kV
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.
