Maximum Ratings

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

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 con-

ditions 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, +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. This parameter is determined by device characterization but is not production tested.
