Counter Dividers Procurement Notes

Verify the specific manufacturer origin as the part number appears associated with multiple vendors including ON Semiconductor and Fairchild. Confirm the package type matches the required DIP or die configuration. Ensure the component meets RoHS compliance standards if applicable to the target assembly process. Cross-reference datasheets from authorized distributors to confirm electrical specifications match the intended application requirements.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with preset capability is required. The AC series offers higher speed compared to standard LS logic while maintaining CMOS power efficiency. Consider the 2V to 6V operating range for compatibility with various logic families. Verify pinout compatibility if replacing legacy designs.

Counter Dividers Part Context

This component is part of the broader 74AC logic family, which provides enhanced performance over earlier generations. It shares functional similarities with other synchronous counters like the 74F163A but differs in technology and speed characteristics. The AC series is designed for applications requiring moderate speed and low power consumption.

Counter Dividers Replacement Considerations

Potential substitutes include the 74F163A for TTL-compatible interfaces or other 74AC163 variants from different manufacturers. Verify pin compatibility and electrical parameters before substitution.
