H = High Voltage Level
L = Low Voltage Level
Hi-Z = High Impedance
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.

Note:
Stresses greater than those listed under MAXIMUM RAT-
INGS 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 sections of this specification is not implied. Ex-
posure to absolute maximum rating conditions for extended
periods may affect reliability.
