MC74HC4020AFG

Counter Dividers Overview

The MC74HC4020AFG 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 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 a maximum clock frequency of 50 MHz at 6.0 V.

Counter Dividers Feature Summary

• Provides 14 master-slave flip-flops with 12 accessible outputs for binary counting
• Features asynchronous active-high reset functionality to force all outputs low
• Compatible with standard CMOS, NMOS, and LSTTL logic families
• Offers high noise immunity characteristic of CMOS devices

Counter Dividers Applications

• Time-base generators requiring precise frequency division
• Digital counters in sequential logic circuits
• Frequency dividers for clock signal processing

Counter Dividers Procurement Notes

Verify the specific suffix 'FG' against official onsemi documentation, as datasheets primarily list 'D' (SOIC-16) and 'DT' (TSSOP-16) packages. Confirm that the component meets AEC-Q100 requirements if automotive qualification is necessary, noting that this typically requires the NLV prefix or -Q suffix. Ensure compatibility with the intended operating temperature range of -55°C to +125°C.

Counter Dividers Selection Notes

Select this component when a 14-bit binary counter with asynchronous reset is required. It is suitable for designs needing direct interface to CMOS, NMOS, and TTL loads. Consider the ripple delay characteristics, as decoded output signals may require gating with the clock signal to avoid decoding spikes in synchronous applications.

Counter Dividers Part Context

This device belongs to the 74HC series of high-speed CMOS logic components manufactured by onsemi. It is functionally identical in pinout to the standard CMOS MC14020B but offers improved performance characteristics typical of the HC family. The component is part of onsemi's standard product line for general-purpose digital logic applications.

Counter Dividers Replacement Considerations

The MC74HC4020A/D serves as a direct replacement for the MC14020B in terms of pinout and functionality. Verify package compatibility between SOIC-16 and TSSOP-16 options if physical footprint constraints exist. Cross-reference with other manufacturers' 14-stage binary counters ensuring matching electrical specifications and reset polarity.
