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
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 cal-
culation should be of the form: T_j = T_a + P * θ_ja where T_a is the ambient temperature, P
is average operating power and θ_ja the thermal resistance of the package. For this
product, use the following θ_ja value:
SOJ: 59^o C/W
TSOP : TBD
