Absolute Maximum Ratings(Note 1)
Recommended Operating
Conditions
(Note 3)
Note 1: 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 lim-
its. The parametric values defined in the Electrical Characteristics tables are not
guaranteed at the absolute maximum ratings. The “Recommended Operating Condi-
tions” table will define the conditions for actual device operation.
Note 2: The input and output negative voltage ratings may be exceeded if the input
and output diode current ratings are observed.
Note 3: Unused logic inputs must be held HIGH or LOW. They may not float.
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) pins.
Note 5: Per TTL driven input (V
IN
3.4V, control input only). A and B pins do not contribute to I
