Flip Flops Procurement Notes

Verify the specific suffix 'ADR' against the manufacturer's official datasheet to confirm the SOIC-14 package type and tape-and-reel packaging format. Ensure that the ordering information matches the exact part number required for your bill of materials, as suffixes define critical physical and handling specifications.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with wide voltage compatibility is required. The LVxA series provides superior speed compared to standard LS logic while maintaining lower power consumption than AC/HCT families. Verify that the 140 MHz maximum frequency meets the system timing requirements and that the 2 V minimum supply voltage aligns with the target logic levels.

Flip Flops Part Context

This device belongs to the SN74LVxA family, which utilizes advanced CMOS technology to achieve high-speed operation with low power dissipation. The LVxA series is designed to interface directly with 3.3 V systems while remaining compatible with 5 V interfaces, making it versatile for mixed-voltage digital designs requiring reliable state retention.

Flip Flops Replacement Considerations

The SN74LV74ADRE4 is a verified equivalent part number representing the same functional device with RoHS compliance enhancements. Cross-reference the pinout and electrical characteristics with the official datasheet before substitution to ensure compatibility with existing board layouts.
