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

¡öWide supply voltage range: 3V to 15V

¡öHigh noise immunity: 0.45 VDD(typ.)

¡öLow power TTL compatibility: fan out of 2 driving 74L or 1 driving 74LS

¡öParallel jam inputs

¡öBinary or BCD decade up/down counting
