(1) All typical values are at TA = 25°C.
(2) Measured by the voltage drop between the SCL1 and SCL2, or SDA1 and SDA2 terminals, at the indicated current through the switch. Minimum ON-state resistance is determined by the lowest voltage of the two terminals.
(3) Measured in current source configuration only. See Figure 7-1
(4) Measured in current sink configuration only. See Figure 7-1
(5) Measured in application connected current source configuration only. See Figure 7-2
