(1) All typical values are at T
A
= 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 sink configuration only (See Figure 4)
