The minimum current required For LOW Level Input 74HC573

[azadfalah]

hi friends

what is The minimum current required For LOW Level Input 74HC573 ?

Thanks,

The 74HC573 is a CMOS circuit.
The input current, high or low, is just leakage current.
You might try the data sheet (gasp) to answer your question.
According to this data sheet (pg 6) the maximum is 1µA.

Perhaps you are thinking of a bipolar TTL 74573 which requires mA of current for a low level on the input.

Is this dynamic current you want as well?

According to this data sheet (pg 6) the maximum is 1µA.

Thank you
This current for high level is equal?

I just want to make sure

it would be educational for you to check this yourself
According to this data sheet (pg 6)

Hi,

Logic HIGH or LOW is defined by voltage, not by current.
This is especially true with CMOS devices.

The input current may change some when going from low to high but it won't go beyond the maximum limit value.
