The MM54HC147J/883QS is a 10-to-4 line priority encoder. It is typically housed in a 16-pin package. The device encodes 10 input lines into a 4-bit binary code. Of the 10 inputs (labeled 0 to 9), only one should be active at any time, and the encoder prioritizes the highest-numbered active input to generate the corresponding 4-bit binary output.
The main functions of the MM54HC147J/883QS include:
- Encoding decimal inputs to binary outputs.
- Prioritization, where the highest-priority input (highest number) is encoded if multiple inputs are active.
The pin configuration generally includes:
- 10 input pins for the decimal digits (0-9).
- 4 output pins for the encoded binary output.
- Additional pins for power supply (Vcc) and ground (GND).
This encoder is commonly used in applications where multiple input signals need to be prioritized and encoded into a smaller number of output lines for further processing.
