Absolute Maximum Ratings
(1)
NOTE: 1. Stresses greater than those listed under ABSOLUTE 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 con-
ditions for extended periods may affect reliability.
2. Appropriate thermal calculations should be performed in all cases and specifically for
those where the chosen package has a large thermal resistance (e.g., TSOP). The cal-
culation should be of the form
: T
j
= T
a
+ P *
is average operating power and
θ
ja
the thermal resistance of the package. For this
product, use the following

values:
