WARNING!
ESD SENSITIVE DEVICE
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 the AD260 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; functional operation of the device
at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum ratings for extended
periods may effect device reliability.
I/O CONFIGURATIONS AVAILABLE
The AD260 is available in several configurations. The choice of
model is determined by the desired number of input vs. output
lines. All models have identical footprints with the power and
enable pins always being in the same locations.

Caution
: Use care in handling unit as contaminants on the bot-
tom side of the unit or the circuit card to which it is mounted will
lead to reduced breakdown voltage across the isolation barrier.
