Overview
The MAX202CPW is a 5-V dual-channel RS-232 line driver/receiver produced by Texas Instruments. This device is designed to provide the electrical interface between an asynchronous communication controller and the serial-port connector, adhering to the TIA/EIA-232-F and ITU v.28 standards. It features a dual charge-pump circuit that allows operation from a single 5-V supply, using four small external capacitors. The MAX202CPW includes two line drivers and two line receivers, offering high-speed data transfer up to 120 kbit/s and robust ±15 kV ESD protection for RS-232 bus pins.
