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.
