SN75189NS TI Quad RS-232 Line Receiver | 14-SO | 4 Receivers, ±30V Input

Product Overview

The SN75189NS is a quad line receiver designed for RS-232 and other data transmission systems. Manufactured by Texas Instruments, this device integrates four independent receivers in a compact 14-SO package. It converts RS-232 voltage levels to TTL-compatible logic levels, making it ideal for interfacing between serial ports and logic circuits. With a wide input voltage range of ±30V and built-in hysteresis, it ensures reliable data reception in noisy environments.
