74F169 Datasheet (NXP) - 4-bit up/down binary synchronous counter

74F169, 4-bit up/down binary synchronous counter

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 each other whe
