Flip Flops Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-20 package variant when sourcing components. Confirm that the manufacturer designation matches Texas Instruments to ensure compatibility with the specified 74HCT logic family characteristics. Check for RoHS compliance status and moisture sensitivity level classifications prior to procurement to align with assembly process requirements.

Flip Flops Selection Notes

Select this component when designing systems requiring eight-bit parallel data storage with synchronous operation. Ensure the design environment maintains the required 4.5V to 5.5V supply voltage range for proper logic threshold levels. Consider the 20-TSSOP package constraints regarding board space and thermal dissipation capabilities during layout planning.
