4-State Synchronous Bidirectional Counter
74F169 4-Stage Synchronous Bidirectional Counter April 1988 Revised September 2000 74F169 4-Stage Synchronous Bidirectional Counter General Description Features The 74F169 is a fully synchronous 4-stage up/downAsynchronous counting and loading counter. The 74F169 is a modulo-16 binary counter. Fea-Built-in lookahead carry capability tures a preset capability for programmable operation, carry Presettable for programmable operation 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.
