Encoding
- An encoder circuit will convert a single input out of several to a binary code on the output.
- A decimal-to-BCD encoder will convert one active input out of ten to a BCD code on the output.
- An octal-to-binary encoder will convert one-of-eight inputs to a 3-bit binary code on the output.
- A priority encoder such as the 74147 will output the proper code for the higher value of two or more active inputs and provide decimal-to-BCD encoding.
- The 74148 IC is an octal-to-binary priority encoder.
