MC74HC4020ANG

Counter Dividers Overview

The MC74HC4020ANG is a 14-stage binary ripple counter manufactured by onsemi in the HC logic series. It utilizes high-performance silicon-gate CMOS technology and operates within a supply voltage range of 2.0 V to 6.0 V. The device contains 14 master-slave flip-flops with 12 stages brought out to pins, providing active-high outputs that divide the clock frequency by powers of two. It features asynchronous active-high reset functionality and negative-edge triggering for the clock input.

Counter Dividers Feature Summary

• Consists of 14 master-slave flip-flops with 12 output stages available externally
• Outputs directly interface to CMOS, NMOS, and TTL loads
• Asynchronous active-high reset forces all Q outputs low
• Negative-edge triggered clock input advances the counter state

Counter Dividers Applications

• Time-base generator circuits
• Frequency division applications
• Binary counting sequences

Counter Dividers Procurement Notes

Verify the specific package suffix 'D' corresponds to the SOIC-16 format required for your PCB footprint. Confirm the operating temperature range meets your environmental specifications. Ensure the component status is reviewed as availability may vary across different distribution channels.

Counter Dividers Selection Notes

Select this component when a 14-bit binary count is required with standard CMOS compatibility. The HC series offers low input current and high noise immunity suitable for general-purpose digital logic. Verify that the maximum clock frequency at your operating voltage supports your system timing requirements.

Counter Dividers Part Context

This part belongs to the MC74HC4020A family of 14-stage binary counters. It is pin-compatible with the standard CMOS MC14020B but offers improved performance characteristics typical of the HC series. The device is designed for general-purpose digital counting and frequency division tasks in electronic systems.

Counter Dividers FAQ

How does the reset function operate?

The reset is asynchronous and active-high. Applying a high level to the Reset pin asynchronously resets the counter to its zero state, forcing all Q outputs low.

What is the trigger type for the clock input?

The clock input is negative-edge triggered. A high-to-low transition on the Clock pin advances the state of the counter.
