Overview
The MAX213IDBR, produced by Texas Instruments, is a 5-V multichannel RS-232 line driver/receiver integrated circuit. This device is designed to provide a reliable and efficient interface between an asynchronous communication controller and the serial-port connector. It operates from a single 5-V supply and includes a dual charge-pump circuit that generates the necessary ±10V for RS-232 signal levels. The MAX213IDBR is part of the MAX200-MAX209, MAX211, and MAX213 family of RS-232 transceivers, known for their integrated charge pump circuitry and single supply operation.
