Notes:
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 A and B pins at indicated current through the switch. On-Resistance is determined by the lower of the
voltages on the two (A & B) pins.
4. This parameter is determined by device characterization but is not production tested.
