74HC147 DIP IC CMOS Logic 10 To 4 Line Priority Encoder (74HC147 IC)

The 74HC147 is a 10 to 4 line priority encoder integrated circuit designed to convert decimal input signals into a 4 bit binary coded output. It accepts up to ten input lines and produces a corresponding binary output based on the highest priority active input.

This IC belongs to the high speed CMOS logic family and provides reliable encoding performance with low power consumption. It is commonly used in keyboard encoding data compression and digital control systems where multiple input signals must be encoded into a binary format. The DIP package allows easy integration into breadboard prototypes and PCB based circuit designs.
