Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
Note:
Stresses greater than those listed under MAX I MUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional
op er a tion of the device at these or any other con-
di tions above those indicated in the operational
sections of this specifi cation is not implied. Exposure to
absolute maximum rating conditions for extended periods
may affect re li abil i ty.

Notes:
1. For Max. or Min. conditions, use appropriate value specifi ed 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.
