DESCRIPTION
Both the register and the counter have individual positive edge triggered clock. In addition, the counter has direct load and clear functions. Expansion is easily accomplished by connecting RCO af the first stage to the count enable of the second stage. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
