Flip Flops Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel specifications. Confirm that the component meets the intended automotive qualification requirements for your specific application zone. Cross-reference the datasheet revision date to ensure compatibility with current design constraints. Validate thermal performance expectations against the specified operating temperature range before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when high-speed synchronous data storage is required in automotive environments. Ensure the 4.5 V to 5.5 V supply voltage aligns with the system power architecture. Consider the TSSOP-16 footprint availability during PCB layout phase. Evaluate the 150 MHz speed requirement against other logic family options if lower power consumption is critical, as ACT series prioritizes speed over low-power efficiency.

Flip Flops Part Context

This part belongs to the SN74ACT174 family of hex D-type flip-flops. It shares functional similarities with non-automotive variants but includes enhanced durability testing for automotive use. The Q1 suffix indicates automotive qualification. It complements other SN74ACT logic gates by providing essential state-holding capabilities in complex digital circuits requiring precise timing and data retention.

Flip Flops Replacement Considerations

Direct substitutes include SN74ACT174PW and SN74ACT174N, though these lack automotive qualification. For equivalent automotive parts, consider SN74HCS174QPWRQ1 for lower voltage or SN74ACT174WBQBRQ1 for different packaging. Verify pinout compatibility and electrical characteristics before substitution.
