The I
OS
 test is applicable to only one ON channel at a time. The duration of this test is less than 1 s.
#
Measured by the voltage drop between the D and S terminals at the indicated current through the switch. ON-state resistance is determined by
the lower of the voltages of the two (D or S) terminals.

r
on(flat)
 is the difference of r
