Procurement Notes

Verify the specific manufacturer datasheet for the LF21064NTR to confirm pinout compatibility and thermal requirements. Ensure the component matches the required 600V offset voltage specification for your application. Cross-reference the package type with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring simultaneous high-side and low-side control for IGBTs. Consider the 600V offset capability and the specific peak source and sink current limits. Evaluate the 10-20V input range against your system's logic levels to ensure proper signal interfacing without additional level shifting.
