CD4026BF

Counter Dividers Overview

The CD4026BF is a synchronous decade counter and divider from the 4000/14000/40000 series, manufactured by Harris Corporation. It features five-bit binary-coded decimal (BCD) counting with a positive edge trigger mechanism. The device operates in an up-counting direction and includes dedicated outputs for driving seven-segment displays. It utilizes CMOS technology and is housed in a 16-lead ceramic dual in-line package (CDIP16). Key electrical parameters include a maximum operating frequency of 3,500,000 Hz at nominal supply voltage, a load capacitance of 50 pF, and an output low current of 0.00036 A. The component supports a wide temperature range from -55 °C to 125 °C.

Counter Dividers Feature Summary

• Synchronous decade counting with positive edge triggering
• Direct drive capability for seven-segment displays via dedicated outputs
• CMOS construction ensuring low power consumption in static operation

Counter Dividers Applications

• Digital display systems requiring direct BCD-to-seven-segment interfacing
• Frequency division circuits in digital logic designs
• Basic counting applications without firmware development requirements

Counter Dividers Procurement Notes

Verify the specific suffix designation when ordering, as variants such as CD4026BF/3 may indicate different pin configurations or bit depths despite similar base part numbers. Confirm that the required package type matches the available inventory, as ceramic DIP options are distinct from plastic equivalents. Ensure compatibility with existing system voltage levels and temperature ratings before finalizing procurement decisions.

Counter Dividers Selection Notes

Select this component when a synchronous decade counter with integrated display driver outputs is required. It is suitable for applications needing deterministic timing and simplicity in basic counting tasks. Consider the 16-lead CDIP package constraints and verify that the positive edge trigger aligns with the system clock polarity. Evaluate the 3.5 MHz maximum frequency limit against the intended operational speed requirements.

Counter Dividers Part Context

The CD4026BF belongs to the extensive 4000/14000/40000 series of CMOS logic devices produced by Harris Corporation. This series is characterized by high noise immunity and wide operating voltage ranges. The CD4026BF specifically addresses the need for combined counting and decoding functions, reducing the component count in digital systems compared to using separate counter and decoder ICs.
