Table 7. Static characteristics...continued

[1]

All typical values are at Tamb = 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. ON-state resistance

is determined by the lowest voltage of the two terminals.

[3]

Guaranteed by design.

[4]

For DC, DC1 (VSSOP8) and GD1 (XSON8U) packages only.
