Procurement Notes

Verify the manufacturer designation, as this component may be supplied by onsemi following corporate restructuring. Confirm the specific package variant matches the required 16-pin SOIC footprint. Ensure that the operating temperature range aligns with industrial standards if deployed in harsh environments. Cross-reference datasheet revisions to confirm pinout consistency with legacy designs.

Selection Notes

Select this component when a dual flip-flop solution is required for low-voltage logic interfacing. The differential output option provides flexibility for noise-sensitive applications compared to single-ended variants. Consider the propagation delay specifications against system clock speeds to ensure timing compliance. Evaluate power consumption requirements relative to other members of the LCX family for optimal efficiency.

Part Context

This part belongs to the 74LCX series, which represents low-voltage CMOS logic designed for 2.5V and 3.3V applications. The series maintains functional compatibility with standard 74-series logic while offering improved speed and lower power consumption. The MTCX suffix typically denotes a tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Direct substitutes include the 74LCX112MX from onsemi. Other potential replacements within the same logic family should be verified for pinout compatibility and electrical parameter equivalence before integration into existing designs.
