The ’AC/’ACT169 is fully synchronous 4-stage up/down counter. The ’AC/’ACT169 is a modulo-16 binary counter. It features a preset capability for programmable operation, carry lookahead for easy cascading and a U/D input to control the direction of counting. All state changes, whether in counting or parallel loading, are initiated by the LOW-to-HIGH transition of the Clock.
