Overview
The MAX202IDR is a 5-V dual-channel RS-232 line driver and receiver produced by Texas Instruments. This device is designed to meet or exceed the requirements of TIA/EIA-232-F and ITU v.28 standards, providing a reliable electrical interface between an asynchronous communication controller and a serial-port connector. The MAX202IDR features a dual charge-pump circuit that allows operation from a single 5V supply, utilizing four small external capacitors. It includes two line drivers and two line receivers, each with ±15kV ESD protection for RS-232 bus pins. The device operates at data signaling rates up to 120kbit/s and has a maximum driver output slew rate of 30V/µs.
