What are the key features of CD4520BPWR?
- Dual independent 4-bit binary up-counters in a single 16-pin package, enabling two separate counting channels without additional ICs
- Schmitt-trigger clock inputs with gated clock enable providing noise-immune counting from slow or noisy clock sources in industrial systems
- 4000-series CMOS operation from 3V to 18V supply with 50 pF load drive for broad compatibility with legacy and modern logic families
What is CD4520BPWR used for?
The CD4520BPWR is used in frequency division, event counting, and digital sequencing circuits within industrial control panels and embedded timing systems. Two independent 4-bit binary counters share a single 16-pin SOIC package, reducing BOM cost and board area in multi-channel pulse counting and divide-by-N frequency prescaler designs. Schmitt-trigger clock inputs enable reliable counting from mechanical switch contacts and noisy sensor signals without requiring external debounce networks.

Frequently Asked Questions
How many independent binary counter channels does the CD4520BPWR contain, and what is the count capacity per channel?
The CD4520BPWR contains 2 independent 4-bit binary up-counters, each counting from 0 to 15 before overflowing. Both channels share a single 16-pin SOIC package, allowing designs to implement dual divide-by-16 frequency stages or two separate event counters without doubling the IC count or board area.
How does the Schmitt-trigger clock input of CD4520BPWR improve counting reliability from noisy sensor signals?
The Schmitt-trigger clock inputs of CD4520BPWR provide hysteresis of typically several hundred millivolts, preventing multiple false counts when slow or noisy clock edges pass through the switching threshold. This makes the device directly connectable to optical encoder outputs, Hall-effect sensors, or mechanical switch contacts without external RC debounce, simplifying circuit design in industrial counting applications.
For a divide-by-256 frequency prescaler design, how can two CD4520BPWR devices be cascaded?
Each 4-bit counter in CD4520BPWR divides by up to 16 per stage, so 4 stages in series achieve a divide-by-65536 ratio. Cascading the carry output of the first channel to the clock of the second within one package provides divide-by-256 in a single 16-pin SOIC, operating at supply voltages from 3V to 18V with 50 pF output loading for clock distribution buffers.
