CD4522BNSRG4 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).
