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 indi-

cated 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 I and Y pin at indicated current through the switch. ON resistance is determined by the lower of the volt-

ages on the two (I,Y) pins.
