Description  
The HD74HC4518 dual BCD counter and the HD74HC4520 dual binary counter consist of two identical, independent,  
internally synchronous 4-stage counters. The counter stages are type D flip-flops, with interchangeable Clock and  
Enable lines for incrementing on either the positive-going or negative-going transition as required when cascading  
multiple stages. Each counter can be cleared by applying a high level on the Reset line. In addition, the HD74HC4518  
will count out of all undefined states within two clock periods. These complementary MOS up counters find primary  
use in multi-stage synchronous or ripple counting applications requiring low power dissipation and/or high noise  
immunity.  
Features  
High Speed Operation  
High Output Current: Fanout of 10 LSTTL Loads  
Wide Operating Voltage: VCC = 2 to 6 V  
Low Input Current: 1 µA max  
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
