4-Stage Synchronous Bidirectional Counter
General Description
The ’F169isa fully synchronous 4-stage up/down counter.
The ’F169isa modulo-16 binary counter. Featuresa preset
capabilityfor programmable operation, carry lookaheadfor
easy cascadinganda U/D inputto controlthe directionof
counting.All state changes, whetherin countingor parallel
loading,are initiatedbythe LOW-to-HIGH transitionofthe
clock.
Features Asynchronous countingand loading Built-in lookahead carry capability Presettablefor programmable operation
