The AC169 is fully synchronous 4-stage up/down counter. The AC169 is a modulo-16 binary counter. It features a preset capability for programmable operation, carry looka-head for easy cascading and a U/D input to control the direction of counting. All state changes, whether in count-ing or parallel loading, are initiated by the LOW-to-HIGH transition of the Clock.
