Note:

Stresses greater than those listed under MAXIMUM

RATINGS may cause permanent damage to the de-

vice. This is a stress rating only and functional opera-

tion 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, +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 guaranteed but not tested.

5. VOH = VCC 0.6V at rated current.

Maximum Ratings

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