Flip Flops Procurement Notes

Verify the specific suffix 'QDRQ1' to confirm the TSSOP-16 package and automotive grade status. Ensure compatibility with the target PCB footprint and soldering profile. Confirm that the design meets the required voltage levels and current drive capabilities for the intended load. Cross-reference the latest datasheet revision for any updates on mechanical dimensions or electrical limits before finalizing procurement.

Flip Flops Selection Notes

Select this component when six synchronized D-type storage elements are required in an automotive application. The HCS series offers lower power consumption compared to standard HC logic while maintaining similar performance. Consider the TSSOP-16 package if space constraints exist. Verify that the 29 MHz maximum clock frequency meets the system timing requirements. Ensure the input voltage levels align with the source logic family.

Flip Flops Part Context

This part belongs to the SN74HCS174 family of hex D-type flip-flops. The 'Q' indicates automotive qualification, while 'D' specifies the SOIC/TSSOP package style. The 'RQ1' suffix typically denotes reel packaging and specific manufacturing codes. It serves as a digital storage element within larger sequential logic circuits, providing state retention for six bits of data.

Flip Flops Replacement Considerations
