MAX3243EIDWR TI RS-232 Transceiver | 28-SOIC | 3V-5.5V, 250kbps

Product Overview

The MAX3243EIDWR from Texas Instruments is a 3V to 5.5V multichannel RS-232 line driver/receiver with ±15kV ESD protection. It features a 1μA shutdown mode, 250kbps data rate, and is ideal for portable or space-constrained applications. The device operates from a single 3V to 5.5V supply, requiring only four external 0.1μF charge-pump capacitors. It includes three drivers and five receivers, making it suitable for applications where multiple RS-232 ports are needed.
