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 ADG749 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.

Overvoltages at IN, S or D will be clamped by internal diodes. Current should be
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. Only one absolute
maximum rating may be applied at any one time.

from one address state to another.
A measure of unwanted signal that is coupled
through from one channel to another as a result
of parasitic capacitance.

The frequency at which the output is attenuated
by –3 dBs.
The voltage drop across the “ON” switch seen on
the On Response vs. Frequency plot as how many
