Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested)
Note:
Storage Temperature ............................................................-40^oC to +125^oC
Supply Voltage to Ground Potential (Inputs & V_CC Only) .... -0.3 to +6.0V
Supply Voltage to Ground Potential (Outputs & D/O Only) -0.3 to +6.0V
DC Input Voltage ....................................................................... -0.3 to +6.0V
DC Output Current .................................................................................20mA
Power Dissipation .............................................................................. 500mW
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 condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure
to absolute maximum rating conditions for ex-
tended periods may affect reliability.
