CD74HC4020E

Counter Dividers Overview

The CD74HC4020E is a 14-stage binary ripple counter manufactured by Harris Corporation. It operates with a supply voltage range of 2 V to 6 V and features an asynchronous master reset input that clears all stages when driven HIGH. The device advances on the negative edge of the clock signal and provides buffered parallel outputs from twelve stages. It utilizes CMOS technology within the HC logic series, supporting operation across a temperature range of -55°C to 125°C in a 16-pin SOIC package.

Counter Dividers Feature Summary

• Asynchronous master reset capability for immediate clearing of all counter stages
• Negative-edge triggered counting mechanism for precise timing synchronization
• Buffered parallel outputs available from twelve internal stages

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation systems
• Event counting applications

Counter Dividers Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments acquired Harris Semiconductor's logic product lines. Ensure the specific suffix matches the required package type and lead finish. Confirm RoHS compliance status through official documentation, as legacy stock may differ from current production runs.

Counter Dividers Selection Notes

Select this component when a high-voltage tolerant 14-bit counter is required. The HC series offers broader voltage flexibility compared to HCT variants. Consider the package availability and thermal characteristics if operating near the upper temperature limits.

Counter Dividers Part Context

This part belongs to the standard 74HC logic family, designed for compatibility with various digital systems. It serves as a fundamental building block for sequential logic designs requiring long counting sequences without external feedback networks.
