Procurement Notes

Verify the specific suffix 'G4' against official Texas Instruments documentation to confirm lead-free status and RoHS compliance details. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the AEC-Q100 qualification level with your system's environmental requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual independent multiplexing is required within an automotive or industrial context. The HC series offers compatibility with standard CMOS logic levels. Consider the SOIC-Narrow-16 package dimensions during layout planning. Verify that the 2 V to 6 V supply range aligns with your system's power rails and that the propagation delay meets your timing constraints.

Part Context

This part is part of the SN74HC25x series of data selectors. It serves as a functional equivalent to other dual 4-to-1 multiplexers in the market but is distinguished by its automotive qualification and specific packaging. The 'NG4' designation indicates the package type and manufacturing attributes defined by Texas Instruments for this specific product line.

Replacement Considerations

Consult official substitution guides for compatible parts such as the SN74HC253DT or SN74HC253QDR. Verify pinout compatibility and electrical specifications before replacing. Ensure any substitute part maintains the same automotive qualification if required by your application.
