CD4020BK

Counter Dividers Overview

The CD4020BK is a 14-bit binary counter from the 4000/14000/40000 series, manufactured by Harris Corporation. It operates asynchronously with negative edge triggering and counts in an up direction. The device utilizes CMOS technology and is housed in a 16-lead ceramic flatpack (CFP) package. Key electrical specifications include a maximum operating frequency of 3,500,000 Hz at nominal supply voltage, a load capacitance of 50 pF, and a maximum output low current of 0.00036 A. It features no load or preset inputs and supports a maximum operating temperature of 125 °C.

Counter Dividers Feature Summary

• Asynchronous 14-bit binary counting capability with negative edge triggering
• Hermetic ceramic flatpack packaging for robust environmental sealing
• Outputs available from 12 stages for flexible bit selection

Counter Dividers Applications

• High-reliability digital timing circuits requiring hermetic sealing
• Frequency division networks in aerospace systems
• Binary counting applications in military-grade instrumentation

Counter Dividers Procurement Notes

Verify component authenticity through authorized Harris Corporation distributors or certified suppliers. Confirm the presence of the F3A suffix if hermetic ceramic construction is required. Ensure compliance with specific project reliability standards, as this part may not meet modern RoHS directives. Request detailed traceability documentation to validate manufacturing origin and lot history prior to procurement.

Counter Dividers Selection Notes

Select the CD4020BK when a high-density, asynchronous 14-bit counter is needed within a sealed environment. Its CMOS architecture offers low power consumption suitable for battery-operated or heat-sensitive systems. The negative edge trigger simplifies interface design with compatible logic families. Consider the CFP package constraints regarding board space and thermal management during system integration.
