Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
(Note 2)
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: Control input must be held HIGH or LOW, it must not float.
Note 3: The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
DC Electrical Characteristics
Note 4: 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 Ports).
Note 5: Per TTL driven Input (V
IN
=
3.4V, Control input only). A and B pins do not contribute to I
