DESCRIPTION/ORDERING INFORMATION
The MAX202 device consists of two line drivers, two line receivers, and dual charge-pump circuit with ±15-k V
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 single 5-V
supply. The device operates at data signaling rates up to kbit/s and maximum of 30-V/µs driver output
slew rate.
