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. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.

4. 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.

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

Maximum Ratings

(Above which the useful life may be impaired. For user guidelines, not tested.)
