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 specifi-

cation is not implied. Exposure to absolute

maximum rating conditions for extended peri-

ods 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.

Note:

1. This parameter is determined by device characterization but is not production tested.

Maximum Ratings

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