SN75C189NS TI RS-232 Interface IC | Quad Line Receiver | 5V, 300kbps

Product Overview

The SN75C189NS is a quad line receiver designed for RS-232 communication interfaces, manufactured by Texas Instruments. It operates from a single 5V supply and features four independent receivers that convert RS-232 voltage levels to TTL-compatible logic levels. The device is ideal for data terminal equipment (DTE) and data communication equipment (DCE) applications, offering robust performance with typical data rates up to 300 kbps. Housed in an SOP-16 package, the SN75C189NS provides a compact solution for multi-channel serial communication.
