HD74HC668 - Synchronous UP/Down Decade/4-bit binary Counter

HD74HC668 Description

HD74HC668/HD74HC669 Synchronous UP/Down Decade Counter Synchronous Up/Down 4-bit binary Counter .
This synchronous presettable decade counter features an internal carry look-ahead for cascading in highspeed counting applications.

HD74HC668 Applications

* Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the countenable inputs and internal gating. This mode of operation helps eliminate the output counting spikes that are normally associated wi
