• Enabling digital signals
• Phase difference detection between reference and input clocks

Inverter Gates Procurement Notes

Verify the specific package variant (TSSOP or WQFN) against the orderable part number suffix. Confirm that the selected component meets the required AEC-Q100 Grade 1 qualification for your automotive application. Ensure design parameters align with the recommended operating conditions, specifically the 1.1V to 3.6V supply range and -40°C to +125°C temperature limits. Check datasheet electrical characteristics for output current capabilities at your target voltage.

Inverter Gates Selection Notes

Select this component when a low-voltage, automotive-qualified XNOR function is required. The 5.5V input tolerance simplifies interfacing with 3.3V or 5V systems while maintaining a lower core supply voltage. Consider the TSSOP-14 package for standard surface-mount assembly or the WQFN package if wettable flank inspection benefits are needed. Ensure the application does not exceed the maximum load capacitance recommendations to maintain signal integrity.

Inverter Gates Part Context

This device belongs to the SN74LVC7266A-Q1 series, designed specifically for automotive electronics. It implements four independent 2-input exclusive-NOR gates in a single package. The LVC technology enables operation at very low voltages while providing fast switching speeds. The Q1 suffix indicates compliance with automotive reliability standards, distinguishing it from commercial grade counterparts.

Inverter Gates Replacement Considerations

Direct replacements include other SN74LVC7266A-Q1 variants with different package options, such as the WBQA (WQFN) version. Verify pinout compatibility and thermal requirements when substituting between TSSOP and WQFN packages. Non-automotive equivalents like the SN74LVC7266A lack the Q1 qualification and should only be used if automotive certification is not required.
