SN74HC4020NSR

Counter Dividers Overview

The SN74HC4020NSR is a 14-stage asynchronous binary ripple-carry counter manufactured by Texas Instruments. It advances on the negative-going edge of the clock pulse and resets to zero when the clear input goes high. The device operates within a supply voltage range of 2 V to 6 V, with a typical propagation delay of 12 ns. It features push-pull outputs capable of driving up to 10 LSTTL loads and consumes a maximum quiescent current of 80 µA.

Counter Dividers Feature Summary

• Provides 14-stage asynchronous binary counting functionality advancing on negative clock edges
• Features an independent asynchronous clear input that resets all outputs to low state
• Supports operation across a wide supply voltage range from 2 V to 6 V
• Delivers standard CMOS output drive capabilities compatible with LSTTL loads

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation for timing applications
• Event counting in digital systems

Counter Dividers Procurement Notes

Verify the specific package designation 'NS' corresponds to the SOP (Small Outline Package) variant before procurement. Confirm RoHS compliance status and lead finish details via the manufacturer's orderable addendum. Ensure handling procedures account for electrostatic discharge sensitivity inherent to CMOS technology.

Counter Dividers Selection Notes

Select this component for designs requiring a 14-bit asynchronous counter with a single supply voltage between 2 V and 6 V. Consider the negative-edge triggering characteristic for clock synchronization requirements. Evaluate the 80 µA maximum supply current against power budget constraints for low-power applications.

Counter Dividers Part Context

This part belongs to the SNx4HC4020 family of 14-bit asynchronous binary counters. It is a catalog version of the military-grade SN54HC4020. The device utilizes HC CMOS process technology to provide high-speed operation while maintaining low power consumption relative to earlier logic families.

Counter Dividers Replacement Considerations

SN74HC4020DR serves as a direct replacement offering identical functionality in a SOIC package format.
