CD54HC4020F3A

Counter Dividers Overview

The CD54HC4020F3A is a military-grade, high-speed CMOS 14-stage ripple-carry binary counter. It operates on a supply voltage range of 2 V to 6 V and supports an extended temperature range from -55°C to 125°C. The device features buffered inputs and outputs with a common reset function that clears all counters to zero upon receiving a high logic level. Clocking occurs on the negative transition of the input pulse.

Counter Dividers Feature Summary

Counter Dividers FAQ

How does the reset function operate?

Applying a high voltage level to the MR (Master Reset) line resets all counter stages to their zero state immediately.

What triggers the count advancement?

The counter state advances by one stage on the negative clock transition of each input pulse applied to the CP pin.
