Notes:
4. Measured by the voltage drop between A and B pins at the indicated current through the switch. On Resistance is
determined by the lower of the voltages on the two (A or B Ports).
5. Parameter is characterized but not tested in production.

7. Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified
range of conditions.
8. Guaranteed by Design.
