SN75C3238EDWR TI RS-232 Transceiver | 28-SOIC | 3V-5.5V, 1Mbps

Product Overview

The SN75C3238EDWR is a high-performance RS-232 transceiver from Texas Instruments, designed for serial communication in industrial and consumer applications. It operates from a single 3V to 5.5V supply, featuring a dual charge-pump that generates ±5.5V RS-232 output levels. The device integrates three drivers and five receivers, making it ideal for multi-channel UART interfaces. Housed in a 28-pin SOIC package, it offers robust ESD protection up to ±15kV (HBM) and supports data rates up to 1Mbps.
