SN74CBT3251: Continuous channel current

Tool/software:

Hi

I'd like to know the definition of "Continuous channel current"  in the Datasheet for SN74CBT3251 Page4.

Is that average (RMS)  or Maximum current ?

Also,   the definition of  "II/O ON-state switch current(5)" in the Datasheet for SN74CBT3253C Page4.

Average(RMS)  or Maximum current?

Thanks,

Murakami
