BCD-to-decimal decoder

BU4028B

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

Of the ten outputs Q

0 to Q9, 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.

•

Features

1) Low power dissipation.

2) Wide range of operating power supply voltages.

3) High input impedance.

4) High fan-out.

5) Direct drive of 2 L-TTL inputs and 1LS-TTL input.
