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

specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

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 VCC = 3.3V, TA = 25°C ambient and maximum loading.

3. Measured by the voltage drop between DI and DO pins at indicated current through the switch. ON-resistance is determined by the lower of the

voltages on the two (DI & DO) pins.

4. This parameter is determined by device characterization but is not production tested.
