The binary counter features direct clear ( CCLR ) and

count-enable ( CCKEN ) inputs. A ripple-carry output ( RCO ) is

provided for cascading. Expansion is accomplished easily for two

stages by connecting ( RCO ) of the first stage to CCKEN of the

second stage. Cascading for larger count chains can be

accomplished by connecting( RCO )of each stage to the counter

clock (CCLK) input of the following stage.
