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 = 5.0V, 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.
