Notes:

1. The algebraic convention, where the most negative value is a minimum and the most positive is a maximum,

is used in this data sheet.

2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.

3. Guaranteed by design

4. ∆RΟΝ = RΟΝ max - RΟΝ min

5. Flatness is defined as the difference between the maximum and minimum value of on-resistance measured.

6. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25ºC.

7. Worst-case isolation is on channel 4 because of its proximity to the COM pin.

Off isolation = 20log VCOM/VNO, VCOM = output, VNO = input to off switch

8. Leakage testing at single supply is guaranteed by testing with dual supplies.
