MC1489P

The MC1489P is a Motorola quad line receiver designed to translate and receive logic signals over longer runs or noisy environments. Typically used where signal integrity must be preserved between boards or across cables, line receivers provide input buffering, level shifting, and improved noise immunity compared to direct logic inputs. The MC1489P integrates four channels in a single package, simplifying board layout while offering consistent input thresholds and protection. Common uses include serial interface buffering, bus line reception, and industrial control signal conditioning. Florida Circuit supplies authenticated Motorola MC1489P parts and can help with application recommendations, such as input protection and proper termination, to maximize reliability. For designers requiring dependable line reception and simplified interface design, the MC1489P is a practical, field-proven option.
