Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
The guaranteed specifications apply only for the test conditions listed.
Note 2:
Refer to RETS185H-2.5 for military specifications.

Note 4:
Parameters identified with boldface type apply at temperature extremes. All other numbers apply at T
A = TJ = 25°C.
Note 5:
Guaranteed and 100% production tested.
Note 6:
Guaranteed, but not 100% production tested. These limits are not used to calculate average outgoing quality levels.
Note 7:
The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating
T
MAX and TMIN, divided by TMAX–TMIN. The measured temperatures are 55°C, 40°C, 0°C, 25°C, 70°C, 85°C, 125°C.
Note 8:
A military RETS electrical specification available on request.
Note 9:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin.
