For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
Typical values are at V
Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
Measured by the 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,B) pins.
This parameter is determined by device characterization but is not production tested.

Note:
Stresses greater than those listed under MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any
other conditions above those indicated in the operational sec-
tions of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
