What are the key features of CD4520BPWRE4?
- Dual independent 4-bit binary up-counter with gated clock input allows two separate counting channels in a single 16-pin TSSOP package, doubling counting capacity without additional ICs
- Schmitt trigger on clock input provides excellent noise immunity and clean clock signal conditioning, enabling reliable counting even in electrically noisy industrial environments
- CMOS 4000-series family with load/preset input and 1.5 MHz maximum operating frequency offers low power consumption and flexible initialization for event counting and frequency division circuits
What is CD4520BPWRE4 used for?
The CD4520BPWRE4 is used in event counting, frequency division, and time-base generation circuits in industrial control, consumer electronics, and digital instrumentation. Its dual counter architecture and gated clock inputs make it ideal for building up/down counters with direction control when paired with external gates, or for independent dual-channel frequency counting. The Schmitt trigger clock input enhances reliability in noisy environments such as motor control boards, relay panels, and field instrumentation.
