BCD-to-decimal decoder

Transcription

1 -to-decimal decoder U0 The U0 is a decoder which converts signals to decimal signals. Of the ten outputs to, those corresponding to the to input codes are set to, and the others are all set to. If inputs to are used and input is used as disabled input, the U0 can also be used as a -of- decoder.
