Flip Flops Procurement Notes

Verify the complete part number against official documentation, as the suffix 'G' indicates RoHS compliance and specific packaging variants may exist. Confirm that the SOIC-20 package matches your PCB footprint requirements. Ensure the 4.5V to 5.5V operating voltage aligns with your system power rails before procurement.

Flip Flops Selection Notes

Select this component when interfacing between CMOS and LSTTL logic families is required due to its input compatibility. The wide industrial temperature range makes it suitable for harsh environments. Consider the 25 ns propagation delay for timing constraints in your design. Verify if the TSSOP variant is preferred for space-constrained applications.
