预置BINARY /十年UP / DOWN COUNTER Presettable Binary/Decade Up/Down Counter
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 VDDtyp.
■Low power TTL compatibility: fan out of 2 driving 74L or 1 driving 74LS
■Parallel jam inputs
■Binary or BCD decade up/down counting
