Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
(Note 3)
Note 1:
Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside datasheet specifi-
cations.
Note 2:
The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 3:
Control inputs must be held HIGH or LOW, they must not float.
DC Electrical Characteristics
Note 4:
Measured by the voltage drop between A and B
n
pins at the indicated current through the switch. On Resistance is determined by the lower of the
voltages on the two (A or B
n
Ports).
Note 5:
Parameter is characterized but not tested in production.

Note 7:
Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified range of conditions.
