Is the value of delta Icc in description of data sheet"scps202a.pdf" of TCA9539 correct?

Other Parts Discussed in Thread: TCA9555, TCA9539, TCA6416


I am comparing the data sheet of TCA6416, and TCA9555 and TCA9539.

I am comparing delta Icc and I/O structure of these three devices.
TCA9555 has pull-up resistance of 100Kohm.
However, TCA6416 and TCA9539 do not have pull-up resistance.
delta Icc of TCA9539 is 1.5mA although delta Icc of TCA6416 are 25/60uA.
The I/O structure of these two devices looks almost the same.
