Other Parts Discussed in Thread: SN74LVC8T245

Hi,

What is expected maximal current consumption on VccB pin of SN74LVC8T245 in B=>A mode (DIR = 0) in case of maximal load on port A?  

 

Thanks, Alexey.

    Hello,

    If you're interested in the static current that would be the Iccb value tabled on page 5 in electrical characteristics, these values will not change significantly with load variation. If you're looking for dynamic changes then I would suggest looking through the following document, it will show you how to use cpd to calculate the power.
