Procurement Notes

Verify the complete ordering code against the manufacturer's official documentation to ensure correct package type and suffix specifications. Confirm that the 'AV' designation aligns with required ESD protection levels for your specific design constraints. Cross-reference thermal resistance values with your PCB layout plan to ensure adequate heat dissipation under maximum load conditions.

Selection Notes

Select this component when high reliability in automotive environments is required. The wide supply voltage range allows flexibility in system design. Ensure input signals remain within the specified common-mode range to maintain accurate comparison. Consider the open-drain output requirement for pull-up resistor selection based on target logic levels and switching speed requirements.
