Flip Flops Procurement Notes

Verify the specific suffix DYYR corresponds to the SOT-23-14 package and tape-and-reel orientation. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 2 V to 6 V supply voltage range and thermal requirements for the intended operating environment.

Flip Flops Selection Notes

Select this component when compact SOT-23 packaging is required for dual flip-flop functionality. The HCS series offers lower power consumption compared to standard HC logic while maintaining similar performance characteristics. Verify that the 42 ns propagation delay meets system timing constraints and that Schmitt-trigger input thresholds are suitable for the signal integrity requirements.
