Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix QM96G4Q1 confirms automotive grade status and RoHS3 compliance. Confirm the 16-SOIC package dimensions match the design footprint. Check for any recent Product Change Notices regarding assembly sites or material updates that may affect long-term availability or regulatory compliance.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when automotive reliability is required alongside high-speed analog switching. Ensure the system operates within the 4.5V to 5.5V single supply range. Compare on-resistance and bandwidth requirements against other 74HC4051 variants if cost is a primary constraint, noting that HCT logic requires specific voltage levels for proper input recognition.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the Texas Instruments CD74HCT405x family of high-speed CMOS analog switches. It is the automotive-qualified variant of the commercial CD74HCT4051. The 'Q1' suffix denotes AEC-Q100 certification. It shares pinout compatibility with standard 74HC4051 devices but differs in voltage thresholds and manufacturing quality controls suited for automotive use.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

CD74HC4051QM96G4Q1 is the non-HCT (HC logic) equivalent with wider voltage tolerance. CD74HCT4051M96 is the commercial grade version without automotive qualification. Nexperia 74HCT4051D,118 is a third-party alternative with similar HCT logic levels but different on-resistance specs.
