NOTES:

11. VIN = input voltage to perform proper function.

12. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.

13. Parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation.

14. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range.

15. Guaranteed but not tested.

16. rON matching between channels is calculated by subtracting the channel with the highest max rON value from the channel with lowest max rON

value, between NC1 and NC2 or between NO1 and NO2.

Test Conditions: V+ = +1.65V to +2V, GND = 0V, VINH = 1.0V, VINL = 0.4V (Note 17, 19),
