MAX202

5-V DUAL RS-232 LINE DRIVER/RECEIVER

WITH ± 15-kV ESD PROTECTION

SLLS576E – JULY 2003 – REVISED APRIL 2007

DESCRIPTION/ORDERING INFORMATION

The MAX202 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 5-V supply. The device operates at data signaling rates up to 120 kbit/s and a maximum of 30-V/ µ s driver output slew rate.
