Procurement Notes

Verify the manufacturer designation carefully, as sources list both Nexperia and NXP USA Inc. for this part number. Confirm the specific suffix '118' corresponds to the correct tape and reel packaging configuration. Ensure the datasheet matches the required 16-TSSOP pinout and electrical characteristics before integration into designs.

Selection Notes

Select this component when dual JK functionality with preset and clear controls is required in low-voltage environments. The wide temperature range makes it suitable for industrial applications. Consider the 16-TSSOP footprint for PCB layout constraints. Verify compatibility with system voltage levels given the 1.2 V minimum operating threshold.

Part Context

This part belongs to the 74LVC logic series, designed for low-voltage CMOS applications. It offers performance comparable to 74HC devices but operates at lower voltages. The dual JK configuration allows for complex sequential logic implementation in a compact surface-mount package, fitting modern miniaturized electronic designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check official manufacturer cross-reference lists for equivalent dual JK flip-flops in the 74LVC or similar families if replacement is necessary.
