Description: Dual decade ripple counter

Features

* Two BCD decade or bi-quinary counters
* One package can be configured to divide-by-2, 4, 5, 10, 20, 25, 50 or 100
* Two master reset inputs to clear each decade counter individually
* Output capability: standard

Applications

* of divide-by-2, 4, 5, 10, 20, 25, 50 or 100. Each section is triggered by the HIGH-to-LOW transition of the clock inputs (nCP0 and nCP1 ). For BCD decade operation, the nQ0 output is connected to the nCP1 input of, the divide-by-5 section. For bi-quinary decade operation, the nQ3 output is connected
