Absolute Maximum Ratings
(Note 2)
Recommended Operating
Conditions
(Note 5)
Note 2:
The
“
Absolute Maximum Ratings
”
are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The
“
Recommended Operating Conditions
”
table will define the conditions
for actual device operation.
Note 3:
V
S
is the voltage observed/applied at either the A or B Ports across
the switch.
Note 4:
The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 5:
Unused control inputs must be held HIGH or LOW. They may not
float.

Note 7:
Measured by the voltage drop between A and B pins at the indicated current through the switch. On Resistance is determined by the lower of the
voltages on the two (A or B) pins.
