The MC1489N is a monolithic quadruple line receiver manufactured by SIG, designed to meet the requirements of the TIA/EIA-232-F standard for interfaces between data-terminal equipment and data-communication equipment. This obsolete part operates from a single 5V supply and offers a maximum data rate of 1Mbps.
Key electrical characteristics include a logic voltage minimum of 5V and an input signal range of ±30V. The device features built-in input hysteresis, providing double thresholds for improved noise immunity. A response control terminal is available for each receiver, allowing for input threshold shifting and input noise filtering through external components.
The MC1489N is available in a 14-pin PDIP package. It has an input resistance between 3 kΩ and 7 kΩ. The operating temperature range is from 0°C to 70°C. Due to its obsolete status, new designs should consider alternate products like the TRS3237E.
This component was designed for applications requiring standard RS-232 communication interfaces. Its features like input hysteresis and response control made it suitable for robust data transmission in various electronic systems.
