Yes, the Typical Operating Characteristic curves for Supply Current (DS4550 datasheet Rev1; 7/17, Page 5) have errors in the supply current units incorrectly shown as Amps (A). The first two curves with VCC=SDA=SCL=TCK depict the device in standby mode and should have units of micro-amps (µA). The next two curves depict the supply current as a function of the TCK and SCL frequency and should have units of milli-amps (mA).
