The performance capability of a high-performance integrated circuit in conjunction with its thermal
environment can create junction temperatures which are detrimental to reliability. The maximum junction
temperature of this integrated circuit should not exceed 125 C.
(1) If the device generating the interrupt has an open-drain output structure or can be 3-stated, a

pull-up resistor is required.
If the device generating the interrupt has a totem-pole output structure and cannot be 3-stated,
a pull-up resistor is not required.
The interrupt inputs should not be left floating.
