Standard ICs

BCD-to-decimal decoder

BU4028B

The BU4028B is a decoder which converts BCD signals to decimal signals.

Of the ten outputs Q

to Q

, those corresponding to the A to D input codes are set to “H”, and the others are all set to

“L”.

If inputs A to C are used and input D is used as disabled input, the BU4028B can also be used as a 1-of-8 decoder.
