MAX222CN

5 - V双RS - 232线路驱动器/接收器，具有±15 - kV ESD保护 5-V DUAL RS-232 LINE DRIVER/RECEIVER WITH +-15-kV ESD PROTECTION

description/ordering information

The MAX222 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. This device meets the requirements of A/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. This device operates at data signaling rates up to 200 kbit/s and a maximum of 30-V/µs driver output slew rate. By using SHDN, all receivers can be disabled.
