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.

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 (VIN 3.4V, control input only). A and B pins do not contribute to ICC.
