SN74AVC8T245: How to calculate power consumption

Part Number: SN74AVC8T245

Hello team,

I received a question from my customer about power consumption of level translator SN74AVC8T245.

How should they calculate the power consumption when using SN74AVC8T245RHL under conditions described in attached graph?

In the datasheet, the power consumption was described in Table1 as current instead of Watts. 

Best Regards,
