Procurement Notes

Verify the specific suffix 'J' against the manufacturer's official ordering information to confirm packaging details. Confirm the active production status directly with Nexperia or authorized distributors, as automotive components may have specific lifecycle constraints. Ensure the selected package variant matches the required PCB footprint for the SOT109-1 outline.

Selection Notes

Select this component when interfacing 15 V logic families with 2.0 V to 6.0 V CMOS circuits requiring inversion. Verify that the operating temperature range of -40 °C to +125 °C meets the environmental requirements. Ensure the propagation delay specifications align with the system timing constraints under the intended supply voltage and load conditions.

Part Context

This part belongs to the 74HC4049-Q100 family of hex inverters designed for automotive reliability. It utilizes standard CMOS technology to provide robust signal conversion. The device integrates six independent inverting channels within a single 16-lead plastic small outline package, offering a compact solution for complex automotive logic interfaces.

Replacement Considerations

Check for other variants within the 74HC4049-Q100 family that may offer different package options or temperature grades. Verify pinout compatibility before substituting with non-Nexperia equivalents to ensure functional equivalence in level shifting applications.
