Notes:
3. Measured by the voltage drop between the A and B pins at the indicated current through the switch. On
resistance is determined by the lower of the voltages on the A or B pins.
4. Flatness is defines as the difference between the maximum and the minimum value on resistance over the
specified range of conditions.
