Datasheet BU4028 DatasheetBU4028 Datasheet (PDF)

Standard ICs BCD-to-decimal decoder BU4028B The BU4028B is a decoder which converts BCD signals to decimal signals. Of the ten outputs Q0 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 dr.
