CD4029BCN Datasheet PDF - Fairchild

●General Description

●The CD4029BC is a presettable up/down counter which counts in either binary or decade mode depending on the voltage level applied at binary/decade input. When binary/decade is at logical “1”, the counter counts in binary, other wise it counts in decade. Similarly, the counter counts up when the up/down input is at logical “1” and vice versa.

●Features

●■Wide supply voltage range: 3V to 15V

●■High noise immunity: 0.45 VDD(typ.)

●■Low power TTL compatibility: fan out of 2 driving 74L or 1 driving 74LS

●■Parallel jam inputs

●■Binary or BCD decade up/down counting
