Dual bidirectional I2C-bus and SMBus voltage-level translator

9.

Static characteristics

[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 and DC1 (VSSOP8) package only.

Table 6.

Static characteristics

Tamb = −40 °C to +85 °C, unless otherwise speciﬁed.
