Procurement Notes

Verify the complete part number including the suffix against official Texas Instruments documentation to ensure correct package type and environmental compliance. Confirm that the specific revision matches your design requirements. Cross-reference with authorized distributors to validate authenticity and traceability before finalizing procurement decisions.

Selection Notes

Select this component when a single-channel decoder or demultiplexer is required in space-constrained designs. The LVC series offers compatibility with standard CMOS logic levels while supporting low-voltage operation. Ensure the SOT-23-6 footprint aligns with your PCB layout constraints and that the electrical specifications meet your system's timing and voltage requirements.

Part Context

This device belongs to the SN74LVC1Gxx series of single-function logic ICs manufactured by Texas Instruments. The LVC family is designed for low-voltage applications, providing performance comparable to older standards while reducing power consumption. The '1G' designation indicates a single circuit per package, optimizing board space for minimal logic functions.

Replacement Considerations

Compatible substitutes include other variants within the SN74LVC1G19 family, such as those with different packaging options like DCKR. Verify pinout compatibility and electrical characteristics before substitution. Ensure any replacement maintains the same logic function and voltage tolerance levels.
