description/ordering information

The MAX207 consists of five line drivers, three 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 devices operate at data signaling rates up to 120 kbit/s and a maximum of 30-V/µs driver output

slew rate.
