MC74HC4020AN

Counter Dividers Overview

The MC74HC4020AN is a high-performance silicon-gate CMOS 14-stage binary ripple counter manufactured by onsemi. It comprises 14 master-slave flip-flops with 12 stages brought out to pins, where each output frequency is half that of the preceding one. The device features asynchronous active-high reset and negative-edge triggering clock input. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• High noise immunity characteristic of CMOS devices
• Outputs directly interface to CMOS, NMOS, and TTL logic families
• Low input current consumption
• Compliance with JEDEC Standard No. 7A requirements

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific package suffix for the MC74HC4020AN against official ordering information, as standard availability may vary. Confirm RoHS compliance and lead-free status through current manufacturer documentation. Ensure the selected variant meets the required automotive or industrial qualification standards if applicable, such as AEC-Q100 for specific suffixes.

Counter Dividers Selection Notes

Select this component for designs requiring a 14-bit binary counter with wide voltage operation. Consider the ripple delay characteristics when decoding outputs, as state changes are not simultaneous. Ensure input rise/fall times remain within specified limits to maintain functional integrity across the full temperature range.

Counter Dividers Part Context

This device belongs to the MC74HC4020A series of high-performance silicon-gate CMOS logic products. It is pin-compatible with standard CMOS MC14020B devices but offers improved performance characteristics typical of the HC family. The series includes variants with different packaging options to suit various assembly requirements.

Counter Dividers Replacement Considerations

The MC74HC4020A/D serves as a direct replacement for the MC14020B in terms of pinout compatibility. Verify electrical specifications and package dimensions when substituting with other manufacturers' equivalents to ensure signal integrity and mechanical fit.
