CD4026AF/3

Counter Dividers Overview

The CD4026AF/3 is a CMOS decade counter and divider manufactured by Harris Corporation. It integrates a ten-stage ripple counter with a decoder to drive seven-segment displays directly. The device features an asynchronous clock input, a carry output for cascading, and a clock inhibit function. It operates within the standard CMOS voltage range and supports parallel load capabilities for data initialization.

Counter Dividers Feature Summary

• Directly drives seven-segment displays via integrated decoding logic
• Asynchronous counting with dedicated carry output for expansion
• Includes clock inhibit control for precise timing management

Counter Dividers Applications

• Digital display systems requiring direct segment driving
• Frequency division circuits in digital signal processing
• Cascaded counter networks for extended counting ranges

Counter Dividers Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets were acquired by other entities. Confirm the suffix 'AF/3' corresponds to the specific package and temperature grade required. Request official datasheets from authorized distributors to ensure component authenticity and traceability before procurement.

Counter Dividers Selection Notes

Select this component when a single IC must handle both counting and display decoding functions. Ensure the operating voltage matches the system's CMOS requirements. Consider the package type availability if industrial temperature ratings are necessary for the specific application environment.

Counter Dividers Part Context

This part belongs to the CD4000 series of CMOS logic devices. It serves as a fundamental building block for digital counting applications. Similar parts include the CD4017, which offers different sequencing outputs. The series is known for low power consumption and high noise immunity in digital circuits.

Counter Dividers Replacement Considerations

The CD4026BF/3 is a documented variant within the same family, often sharing functional compatibility but potentially differing in package or temperature specifications. Verify pinout and electrical characteristics against the original design requirements before substitution.
