General Description
The AC169 is a fully synchronous 4-stage up/down counter. The AC169 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 transistion of
the Clock.
