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 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 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.

pin.
Note 7:
Per TTL driven input, control pins only.
