描述：
CD4522B programmable BCD counter has a decoded 0 state output for divide-by-N applications. In single stage operation the 0 output is tied to the Preset Enable input. The Cascade Feedback allows multiple stage divide-by-N operation without the need for external gating. A HIGH on the Clock Inhibit disables the pulse-counting function. A HIGH on the Master Reset asynchronously resets the divide-by-N operation. The output is presented in BCD format.
The CD4522B-series types are supplied in 16-lead dual-in-line plastic packages (E suffix)， 16-lead small-outline packages (M， M96， MT， and_NSR suffixes)， and_16-lead thin shrink small-outline packages (PW and_PWR suffixes).
