SN74148N 8-to-3 Line Priority Encoder IC

The SN74148N is a high-performance 8-to-3 line priority encoder designed for use in digital logic and control applications. This IC efficiently converts eight active-LOW input signals into a 3-bit binary output, while also providing priority handling ensuring that when multiple inputs are active simultaneously, the highest-priority input is encoded first. Built using TTL (Transistor-Transistor Logic) technology, the SN74148N offers fast switching speeds and reliable operation, making it ideal for use in microprocessor systems, data routing, interrupt control circuits, and digital communication equipment. Additional features such as enable inputs and cascade outputs allow easy expansion for larger encoding systems.

Housed in a standard DIP-16 package, this IC is simple to integrate into breadboards, prototypes, and permanent PCB designs. Whether you are a student, hobbyist, or professional engineer, the SN74148N is a dependable choice for priority encoding tasks in classic and modern digital electronics projects.
