Flip Flops Procurement Notes

Verify the complete part number including suffixes such as 'G' for RoHS compliance when sourcing. Confirm package type accuracy, as variants exist in SOIC and SSOP formats. Cross-reference manufacturer datasheets for specific electrical parameters relevant to your operating conditions. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity. Check for obsolescence notices or lifecycle status updates from onsemi before finalizing procurement plans.

Flip Flops Selection Notes

Select this component when a hex D-type flip-flop with asynchronous reset is required in a compact surface-mount package. Consider the 2V to 6V operating range for flexibility in low-voltage applications. Evaluate propagation delay specifications against system timing requirements. Compare pinout compatibility with existing designs if replacing legacy parts. Assess power consumption needs relative to other logic families for efficiency optimization.

Flip Flops Part Context

This component belongs to the 74HC174A family of hex D-type flip-flops. It is functionally similar to other industry-standard hex flip-flops but offers specific onsemi manufacturing attributes. The 'AFR2' designation indicates a specific tape-and-reel packaging variant suitable for automated assembly processes. It complements onsemi's broader portfolio of high-speed CMOS logic devices designed for general-purpose digital applications.

Flip Flops Replacement Considerations

Direct substitutes include MC74HC174ADTR2G and MC74HC174ADR2G, which share identical logical functionality but differ in package style (TSSOP vs SOIC). Verify pinout compatibility when switching between different package types. Ensure voltage and current specifications meet application requirements across all candidate parts.
