ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

Stresses above those listed under “Absolute Maximum Ratings”
may cause permanent damage to the device. This is a stress
rating only and functional operation at or above this specifica-
tion is not implied. Exposure to above maximum rating
conditions for extended periods may affect device reliability.
MIL-STD-883
The rigors of the military and aerospace environment, temp-
erature extremes, humidity, mechanical stress, etc., demand the
utmost in electronic circuits. The AD394, with the inherent
reliability of an integrated circuit construction, was designed
with these applications in mind. The hermetically-sealed, low
profile DIP package takes up a fraction of the space required by
equivalent modular designs and protects the chips from
hazardous environments. To further insure reliability, the
AD394 is fully compliant to MIL-STD-833 Class B, Method
5008.
