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 I and Y pin at indicated current through the switch. ON resistance is determined by the
lower of the voltages on the two (I,Y) pins.
4. This parameter is determined by device characterization but is not production tested.

Note:
Stresses greater than those listed under MAXIMUM RATINGS 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
specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
