SN74147N 10-to-4 Line Priority Encoder IC

The SN74147N 10-to-4 Line Priority Encoder is a TTL logic IC designed to encode ten active-LOW input lines into a 4-bit binary output. When multiple inputs are active simultaneously, the encoder assigns priority to the highest-numbered input, ensuring accurate and predictable output an essential feature in complex digital systems. This IC is widely used in keyboard encoding, interrupt handling, data compression, and control logic applications where multiple signals must be efficiently processed. The SN74147N features active-LOW inputs and outputs, making it fully compatible with standard TTL logic circuits. Its fast response time and stable performance make it suitable for both educational and industrial electronic designs.

Packaged in a 16-pin DIP, the SN74147N is easy to integrate into breadboards and PCBs, making it an excellent choice for students, hobbyists, and engineers working with classic digital logic or microprocessor interfacing projects.
