MC74HC4020AFL1

Counter Dividers Overview

The MC74HC4020AFL1 is a 14-bit binary counter integrated circuit manufactured by onsemi. It operates within a supply voltage range of 2 V to 6 V and supports a maximum counting rate of 50 MHz. The device features asynchronous reset functionality and negative-edge triggered flip-flops. It is housed in a 16-SOEIAJ surface-mount package and is rated for an operating temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Provides 14-bit binary up-counting capability using negative-edge triggered flip-flops.
• Includes an asynchronous reset input for immediate clearing of the count state.
• Operates reliably across an extended industrial temperature range from -55°C to 125°C.

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in digital logic systems
• Timing and control applications requiring extended temperature operation

Counter Dividers Procurement Notes

Verify the specific package designation, as MC74HC4020AFL1 corresponds to the 16-SOEIAJ form factor. Confirm that the required supply voltage and temperature range align with your system specifications. Check current availability status as this component may be subject to lifecycle changes or obsolescence notices from the manufacturer.

Counter Dividers Selection Notes

Select this component when a 14-bit binary counter is required in a compact 16-pin surface-mount package. Ensure the design accommodates the 2 V to 6 V supply range and 50 MHz speed limit. Consider the 16-SOEIAJ footprint compatibility during PCB layout. Verify thermal requirements against the -55°C to 125°C operating range.

Counter Dividers Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It functions as a ripple counter, distinct from synchronous counters found in other series. The 14-bit depth allows for significant counting ranges without cascading multiple chips, simplifying board space requirements compared to lower-bit alternatives.

Counter Dividers Replacement Considerations

Direct substitutes include MC74HC4020ADR2G (16-SOIC) and MC74HC4020ADTR2G (16-TSSOP). These variants offer identical electrical performance but differ in physical package dimensions. Verify pin-to-pin compatibility and footprint suitability before substitution.
