4-bit up/down binary synchronous counter

DESCRIPTION The 74F169 is a 4-bit synchronous, presettable Modulo 16 up/down counter featuring an internal carry look-ahead for applications in high-speed counting designs. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with

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
