Note: Stresses greater than those listed under MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this
speciï¬cation is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

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