74HC148 DIP IC 8 Line To 3 Line Priority Encoder (74HC148 IC)

The 74HC148 is an 8 line to 3 line priority encoder integrated circuit designed to convert multiple input signals into a compact binary coded output. It accepts up to eight input lines and produces a 3 bit encoded output representing 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 digital control circuits interrupt systems and data encoding applications where multiple signals must be prioritized and converted into binary form. The DIP package allows easy integration into breadboard prototypes and PCB based circuit designs.
