CD4518BMS Dual BCD Up Counter and CD4520BMS Dual  
Binary Up Counter each consist of two identical, internally  
synchronous 4-stage counters. The counter stages are  
D-type flip-flops having interchangeable CLOCK and  
ENABLE lines for incrementing on either the positive-going  
or negative-going transition. For single unit operation the  
ENABLE input is maintained high and the counter advances  
on each positive-going transition of the CLOCK. The  
counters are cleared by high levels on their RESET lines.

The counter can be cascaded in the ripple mode by connect-  
ing Q4 to the enable input of the subsequent counter while  
the CLOCK input of the latter is held low.
