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 maxi-
mum rating conditions 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
calculation should be of the form: Tj = Ta + P * θja where Ta is the ambient tempera-
ture, P is average operating power and θja the thermal resistance of the package. For
this product, use the following θja values:
SOJ: 78 oC/W
TSOP: 112 oC/W
