The 74LS148 is a priority encoder that converts eight active-low inputs into a 3-bit binary output representing the highest-priority active input. Ideal for interrupt handling, keyboard scanning, and priority-based control systems where only the most important digital signal needs immediate attention from a microcontroller.
Key Features
- 8 active-low inputs condensed to 3-bit binary priority output
- Interrupt enable (EI) and group select outputs
- Cascadable for larger priority hierarchies
- Standard DIP-16 package for breadboards and PCBs
- TTL logic levels (5V compatible)
- Useful for emergency stop buttons, alarm systems, and sensor priority logic
