74F169 4-Stage Synchronous Bidirectional Counter April 1988 Revised July 1999 74F169 4-Stage Synchronous Bidirectional Counter General Description The 74F169 is a fully synchronous 4-stage up/down counter. The 74F169 is a modulo-16 binary counter. 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-toHIGH transition of the clock. Features s Asynchronous counting and loading s Built-in lookahead carry capability s Presettable for programmable operation Ordering Code: Order Number 74F169SC 74F169SJ 74F169PC...
