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 con-  
trol the direction of counting. All state changes, whether in  
counting or parallel loading, are initiated by the LOW-to-  
HIGH transition of the Clock.
