Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values, except differential voltages, are with respect to the network ground.
Differential voltages are at IN+ with respect to IN–.
This input current exists only when the voltage at any of the inputs is driven negative. The current flows through the collector-base
junction of the input clamping device. In addition to the clamping device action, there is lateral n-p-n parasitic transistor action. This
action is not destructive, and normal output states are reestablished when the input voltage returns to a value more positive than –0.3 V
at T
= 25
°
C.
Short circuits between outputs to V
can cause excessive heating and eventual destruction.
If the output transistors are allowed to saturate, the low-bias dissipation and the on-off characteristics of the outputs keep the dissipation
very small (usually less than 100 mW).
Maximum power dissipation is a function of T
(max),
θ
, and T
. The maximum allowable power dissipation at any allowable ambient
temperature is P
= (T
(max) – T
)/
θ
. Operating at the absolute maximum T
of 150
°
C can impact reliability.
The package thermal impedance is calculated in accordance with JESD 51 (low-K board).
