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” table are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” 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 control inputs must be held HIGH or LOW. They may not
float.

Note 4: All typical values are at V_CC = 5.0V, T_A = 25°C.
Note 5: Measured by voltage drop between A and B pin at indicated current through the switch. On Resistance is determined by the lower of the voltages on
the two (A or B) pins.
Note 6: Per V_CC pin.
Note 7: Per TTL driven input, control pins only.
