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 ADG774A 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.

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
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 condi-
tions for extended periods may affect device reliability. Only one absolute maxi-
mum rating may be applied at any one time.
2
Overvoltages at IN, S or D will be clamped by internal diodes. Current should be
limited to the maximum ratings given.

t
ON
Delay between applying the digital control input
and the output switching on. See Test Circuit 4.
t
OFF
Delay between applying the digital control input
and the output switching Off.
t
D
“OFF” time or “ON” time measured between
the 90% points of both switches, when switching
from one address state to another. See Test
Circuit 5.
Crosstalk
A measure of unwanted signal that is coupled
through from one channel to another as a result
of parasitic capacitance.
Off Isolation A measure of unwanted signal coupling through an
“OFF” switch.
Bandwidth
