About additional quiescent supply current of PCAL6524

[kazuhiroozuchi]

In p.6 of the data sheet for PCAL6524 has the following description of additional quiescent supply current.

ADDR, SCL, SDA, RESET; one input at VDD(I2C-bus) - 0.6 V, other inputs at VDD(I2C-bus) or VSS; VDD(P) = 1.65 V to 5.5 V

max 25uA

P port; one input at VDD(P) - 0.6 V, other inputs at VDD(P) or VSS; VDD(P) = 1.65 V to 5.5 V

max 80uA

It is a very high current as a quiescent supply current, but does it mean that a large quiescent supply current will flow if one port is 0.6 V lower than VDD?

The above-mentioned quiescent supply current does not occur if input voltage is within VDD-0.6V?

Hi,

Different un-characterized quiescent supply current will flow if one port is 0.6 V lower than VDD, but the mentioned in the datasheet quiescent supply current occurs if input voltage is within VDD-0.6V.
