What is CD4520BPWRG4 used for?
The CD4520BPWRG4 is used for frequency division, event counting, and sequential timing circuits in microcontroller-based systems, industrial process controllers, and consumer electronics. Its dual 4-bit counter configuration allows cascading to form 8-bit or longer counters, or independent use of each counter for two separate count channels on one IC. The Schmitt trigger clock input makes it particularly useful for counting signals from mechanical switches, encoders, and low-slew-rate digital sources without glitching.

Frequently Asked Questions
Which counting functions does CD4520BPWRG4 support in logic designs?
CD4520BPWRG4 is a CMOS dual 4-bit binary up-counter, so it can divide clocks, count events, or build simple sequencing logic up to 1.5 MHz.
How does the SOIC package influence PCB layout for this counter?
The part is supplied in a 16-pin SOIC-style small-outline package, which fits standard SMT assembly while exposing clock, reset, and counter output signals.
Why is the Schmitt trigger clock input useful in industrial control circuits?
The Schmitt trigger clock input improves tolerance of slower or noisier edges, and the fetched 50 pF load capacitance context helps designers budget external logic loading.
When should procurement prefer this G4 ordering option over an alternate logic counter?
Use this Texas Instruments 4000B-family option when the BOM needs a 16-pin CMOS counter with e4 finish tracking and compatible CD4520B logic behavior.
