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/µs driver output slew rate.
