74HC147 - 10-to-4 Line Priority Encoder
The 74HC147 is a high-speed CMOS 10-to-4 line priority encoder. It encodes 10 input lines (active low) into a 4-bit binary output. The IC gives priority to the highest-numbered active input to determine the output. It is ideal for keyboard encoding and data compression applications.
Specifications:
- Logic Type: 10-to-4 line priority encoder
- Input Logic: Active LOW
- Output Format: 4-bit binary
- Supply Voltage Range: 2V to 6V (typically 5V)
- Maximum Input Current: ±1 µA
- Propagation Delay: ~13 ns at VCC = 5V
