MC74HC4020AFELG

Counter Dividers Overview

The MC74HC4020AFELG is a high-performance silicon-gate CMOS 14-stage binary ripple counter. It consists of 14 master-slave flip-flops with 12 stages brought out to pins, where each output divides the preceding frequency by two. The device features an asynchronous active-high reset and negative-edge triggering clock input. It operates within a voltage range of 2.0 V to 6.0 V and supports propagation delays from 25 ns at 6.0 V to 96 ns at 2.0 V.

Counter Dividers Feature Summary

• Contains 14 master-slave flip-flops with 12 accessible output stages for binary counting
• Features asynchronous active-high reset functionality that forces all outputs low
• Provides negative-edge triggered clock input for state advancement
• Outputs directly interface with CMOS, NMOS, and TTL logic families

Counter Dividers Applications

• Time-base generator circuits requiring precise frequency division
• Digital counters for event tracking and measurement systems
• Frequency dividers in signal processing applications

Counter Dividers Procurement Notes

Verify the specific suffix 'AFELG' against official onsemi documentation to confirm package type and automotive qualification status. Ensure the ordering code matches the required tape and reel specifications or bulk packaging options. Confirm RoHS compliance and lead-free status as stated in the datasheet revision history.

Counter Dividers Selection Notes

Select this component when a 14-stage binary counter with 12 external outputs is required. It is suitable for designs needing direct interfacing with standard CMOS and TTL loads. Consider the operating temperature range of -55°C to +125°C for industrial environments. Verify power supply constraints align with the 2.0 V to 6.0 V operating range.

Counter Dividers Part Context

This part belongs to the HC series of high-speed CMOS logic devices manufactured by onsemi. It is functionally identical in pinout to the standard CMOS MC14020B but offers improved switching speeds and noise immunity characteristic of modern silicon-gate technology. The device is designed for general-purpose digital counting applications.

Counter Dividers Replacement Considerations

The MC74HC4020A is pin-compatible with the MC14020B. Verify electrical characteristics such as propagation delay and drive capability when substituting older CMOS variants. Ensure the replacement device meets the required voltage and temperature specifications for the target application.
