MC1489AP

The MC1489AP is a through-hole PDIP14 quad line receiver from Motorola, suitable for prototyping, repairs, and legacy board designs that prefer socketable components. Line receivers like the MC1489AP improve noise immunity and provide consistent input thresholds for signals traveling across cables or noisy PCB traces. With four buffered inputs in a single package, the part simplifies wiring and reduces discrete component count for interface applications. The device is commonly used in serial interfaces, multi-drop bus systems, and industrial control panels where robust reception and level translation are required. Florida Circuit supplies authenticated Motorola components and can assist with layout guidance and sourcing for batch orders. For engineers working on mixed-generation hardware or refurbishing older equipment, the MC1489AP is a dependable, easy-to-use receiver IC.
