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, +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.
