Flip Flops Procurement Notes

Verify that the ordered part number matches MC74LVX574DWR2G exactly, ensuring the suffix indicates the correct SOIC-20 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for any recent product change notifications regarding pinout or electrical characteristics updates. Ensure supply chain sources are authorized distributors to guarantee component authenticity and traceability.

Flip Flops Selection Notes

Select this component when designing low-voltage digital systems requiring octal storage with bus-compatible outputs. The LVX series offers superior speed compared to standard LV logic while maintaining low power consumption. Consider the 18 ns propagation delay and 75 MHz clock limit for timing analysis. The SOIC-20 package is suitable for space-constrained PCB layouts. Evaluate input capacitance and output drive strength against load requirements to ensure signal integrity.

Flip Flops Part Context

This device belongs to the 74LVX family of mixed-signal CMOS logic ICs, designed for low-voltage operation. It complements other octal flip-flops like the MC74AC574 but targets lower voltage domains. The DWR2G suffix denotes the specific tape-and-reel packaging variant. It serves as a foundational building block for sequential logic design in portable and battery-powered electronic devices.
