NOTES:
4. V_IN = input voltage to perform proper function.
5. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
6. Parts are 100% tested at +25°C Over-temperature limits established by characterization and are not production tested.
7. Limits established by characterization and are not production tested.
