SN74LVC2G79: power consumption question

Cameron Perl

Part Number: SN74LVC2G79

Hey team,

How would we best calculate the estimated power consumption of the SN74LVC2G79DCUR based on power dissipation capacitance and operating frequency operating at 1.8V and 48MHz

Thanks,

Cameron

Hi Cameron,

Please take a look at [FAQ] How do I Calculate Power Consumption or Current Consumption for my CMOS Logic Device? for a detailed explanation and equations. There's also a handy Excel document that you can use as a power calculator. I calculate 18nW of static power consumption and 7.2mW of dynamic power consumption if both channels of the SN74LVC2G79 are switching at the same time. The FAQ also links to an application note with a lot more information. Take a look if you're interested.

Regards,

Nikki
