= 10V. Indicator outputs have 2k
pull-up resistors. All electrical ratings and specifications
are tested with the inverting over-voltage input and the non-inverting under-voltage input externally connected to the 2.5V reference. Low duty cycle
testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)

THERMAL DATA
Note A. Junction Temperature Calculation: T
= T
+ (P
x
θ
).
Note B. The above numbers for
θ
are maximums for the limiting
thermal resistance of the package in a standard mount-
ing configuration. The
θ
numbers are meant to be
guidelines for the thermal performance of the device/pc-
board system. All of the above assume no ambient
airflow.
