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.

Notes:

1. For Max. or Min. conditions, use appropriate value specified 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 A and B pin 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.
