Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against current ON Semiconductor databases, as Fairchild part numbers with underscores may have been updated to dashes. Confirm the package type matches the 12-lead Ultrathin MLP specification. Ensure compliance with RoHS standards and check for any recent product change notices regarding manufacturing sites or material composition updates prior to finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring bi-directional voltage translation between 1.65V and 5.5V without dedicated direction control lines. It is suitable for I2C applications needing integrated pull-ups and bus isolation features. Consider the 12-lead Ultrathin MLP package for space-constrained designs. Verify that the application does not require non-standard voltage ranges outside the specified operating conditions.
