SN75189N TI Quad RS-232 Line Receiver | 14-PDIP | 5V, 300 bps

Product Overview

The SN75189N is a monolithic quad line receiver designed to meet the specifications of RS-232 serial communication standard. Manufactured by Texas Instruments, this device is housed in a 14-pin PDIP package. It converts RS-232 voltage levels to TTL-compatible logic levels, making it ideal for interfacing between serial ports and logic circuits. The SN75189N features input hysteresis for noise immunity and operates from a single 5V supply.
