Counter Dividers Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers, as the manufacturer has ceased production. Confirm that the specific lot matches the original Harris Corporation specifications. Request detailed traceability documentation to ensure compliance with quality standards. Inspect physical markings for accuracy against official datasheet references. Validate electrical performance parameters upon receipt to confirm operational integrity before integration into final assemblies.

Counter Dividers Selection Notes

Select this component when a synchronous four-bit binary counter with preset capabilities is required. Ensure the design accommodates the specified voltage range and temperature constraints. Consider the package dimensions for PCB layout compatibility. Verify that the synchronous reset feature aligns with system timing requirements. Evaluate alternative sources if new production availability is critical for long-term manufacturing.

Counter Dividers Part Context

This part belongs to the AC logic family of integrated circuits, designed for high-speed digital applications. It serves as a fundamental building block for sequential logic systems requiring precise state management. The synchronous nature of the counter ensures stable transitions without race conditions common in asynchronous designs. Its robust construction supports reliable operation in demanding electronic environments.

Counter Dividers Replacement Considerations

Compatible substitutes include the CD74AC163ME4 and CD74AC163M96. These variants maintain functional equivalence while potentially differing in packaging suffixes or lead content compliance. Verify pinout compatibility and electrical characteristics before substitution.
