HD74HC668 counter equivalent, synchronous up/down decade/4-bit binary counter.
an internal carry look-ahead for cascading in highspeed counting applications. Synchronous operation is provided by having all flip-flops clocked simultaneously so that t.
Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident.
