Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status prior to integration. Ensure ESD protection protocols are followed during handling. Validate package markings against official datasheet specifications. Check for obsolescence notices or lifecycle changes from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when dual independent flip-flops are required in a compact surface-mount footprint. Consider the 2V to 3.6V operating range for compatibility with modern low-voltage logic families. Evaluate the 85 MHz clock frequency capability against system timing requirements. Compare pinout compatibility with existing designs if substituting similar logic devices.

Part Context

This part belongs to the Fairchild 74LVX series of advanced low-voltage CMOS logic devices. The series offers performance comparable to standard 5V TTL logic while operating at significantly lower voltages. The 74LVX74 variant specifically provides dual flip-flop functionality within a single package, optimizing board space for complex digital systems.

Replacement Considerations

Direct substitutes include MC74LVX74MG from onsemi. Verify pin compatibility and electrical specifications before substitution. Check for any packaging differences between SOIC and alternative form factors.
