Notes for Page 2:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at V_CC = 3.3V, T_A = 25°C ambient and maximum loading.
3. Measured by the voltage drop between D_I and D_O pins at indicated current through the switch. ON-resistance is determined by the lower of the
voltages on the two (D_I & D_O) pins.
4. This parameter is determined by device characterization but is not production tested.
