Flip Flops Procurement Notes

Verify the specific suffix against the official datasheet to confirm package type and tape/reel specifications. Ensure the ordered part matches the required TSSOP-14 configuration and voltage ratings. Cross-reference RoHS compliance status as per manufacturer declarations. Confirm availability through authorized distributors to avoid counterfeit components.

Flip Flops Selection Notes

Select this component when dual D-type storage is required in space-constrained designs. The LCX series offers lower power consumption compared to standard CMOS logic. Verify that the system voltage falls within the 2V to 3.6V range. Consider the 8 ns propagation delay for timing constraints. Ensure input levels are compatible with the single-ended input structure.

Flip Flops Part Context

This device belongs to the 74LCX family of low-voltage CMOS logic ICs. It serves as a fundamental building block for sequential logic circuits. The dual configuration allows for compact implementation of state machines or data registers. It complements other LCX series gates and buffers in mixed-signal environments requiring low voltage operation.

Flip Flops Replacement Considerations

Check for direct pin-compatible alternatives such as MC74LCX74DR2G or MC74LCX74MTCX depending on the required package format (SOIC vs TSSOP). Verify electrical parameters match before substitution. Ensure functional equivalence regarding set/reset behavior and output drive strength.
