Binary counters are great components when working with logic level circuits. When working with a binary counter, you simply need a clock input in the form of a square wave that gives a signal into the CP1 pin. The pin Q0 should externally be connected to the CP1 pin to ensure that the counter will count upward in binary. This binary counter works with a falling edge on the clock signal to switch to the next number, which means that the output of the counter will change every time when the clock signal transitions from a logic high to a logic low.

The LS family of logic gates can communicate with the HCT and VHC families, which are the more common families in modern circuits since they are able to communicate with almost all the other families of logic level gates. This makes it convenient, because you do not have to stick to a specific family, and you can mix the families as needed when some gates are not available at a store near you.
