Flip Flops Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel specifications. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the component source is an authorized distributor to guarantee authenticity and traceability. Cross-reference the full part number against current obsolescence notices to avoid supply chain disruptions during production planning.

Flip Flops Selection Notes

Select this component when designing systems requiring multiple synchronized data storage elements with low power constraints. The AC series offers a balance between speed and power efficiency compared to standard TTL or older CMOS families. Consider the TSSOP-16 package dimensions for PCB layout compatibility. Evaluate the asynchronous clear functionality against system reset requirements to ensure proper initialization behavior during power-up sequences.

Flip Flops Part Context

This device belongs to the MC74AC family of high-speed CMOS logic devices produced by onsemi. The AC series is designed to be pin-compatible with previous generations while offering improved performance characteristics. It serves as a fundamental building block for sequential logic circuits, enabling complex digital designs through modular integration of basic storage elements within standardized industrial temperature ranges.

Flip Flops Replacement Considerations

Direct substitutes include other hex D-type flip-flops from compatible logic families such as the MC74HC174 or MC74HCT174, provided voltage levels and speed requirements align. Verify pinout compatibility and electrical characteristics before substitution. Alternative packages like SOIC-16 may require adapter considerations if board space permits.
