Flip Flops Procurement Notes

Verify the specific suffix RM13TR against official STMicroelectronics documentation to confirm the tape and reel packaging format and pin assignment. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and authenticity before procurement.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with HCT-compatible input thresholds is required for 5V logic applications. Consider the 20-TSSOP package size constraints and the need for a master reset feature. Evaluate the propagation delay specifications against system timing requirements to ensure adequate performance margins for the intended clock frequencies.
