Flip Flops Procurement Notes

Verify the exact suffix against official onsemi documentation, as 'MC74LVX74DR2' may represent a partial or variant designation. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Check for obsolescence notices or PCN updates that may affect long-term supply. Ensure the package type matches your PCB footprint specifications before ordering.

Flip Flops Selection Notes

Select this component when dual edge-triggered storage elements are required in low-voltage environments. Consider the 13.2ns propagation delay and 85MHz speed for timing-critical paths. Evaluate the 14-SOIC package constraints against board space limitations. Compare against other LVX family members if single-element or octal configurations better suit the system architecture.

Flip Flops Part Context

This part belongs to the 74LVX series, which utilizes silicon gate CMOS technology for high-speed operation. It is functionally compatible with standard 74LS logic families but operates at lower voltages. The base product number 74LVX74 indicates a dual D-flip-flop configuration. This series is designed for applications requiring fast switching speeds with reduced power consumption compared to older logic technologies.

Flip Flops Replacement Considerations

Public confirmed substitutes include 74LVX74MTCX. Verify pinout and electrical characteristics match before substitution.
