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 limits. The parametric values defined in the Electrical

Characteristics tables are not guaranteed at the absolute maximum ratings.

The Recommended Operating Conditions tables 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 control 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: Typical values are at VCC = 5.0V and TA= +25°C
