Flip Flops Procurement Notes

Verify the specific ordering suffix matches the required package variant and tape/reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the procurement channel is authorized to guarantee component authenticity and traceability. Check for any recent product lifecycle notices regarding availability or obsolescence before finalizing orders.

Flip Flops Selection Notes

Select this component when a hex D-type flip-flop with TTL-compatible inputs is required. The AHCT series ensures compatibility with 5 V CMOS and TTL logic families. Consider the 16-pin SOIC package for surface-mount assembly constraints. Evaluate the 115 MHz clock speed against system timing requirements. Verify that the 4.5 V to 5.5 V supply range aligns with the target circuit design.
