ABSOLUTE MAXIMUM RATINGS(1)

NOTES:

1. Stresses greater than those listed under ABSOLUTE 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.

DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE

FollowingConditionsApplyUnlessOtherwiseSpecified:

Industrial: TA = –40°C to +85°C, VCC = 5.0V ± 5%, BIASV = 0 to VCC

NOTES:

1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at VCC = 5.0V, +25°C ambient.

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

4. Measured by voltage drop between ports at indicated current through the switch.
