SN74LV4066A: SN74LV4066APWR MAXIMUM POWER CONSUMPTION AND THE EQUATION

Mandy Lin

Part Number: SN74LV4066A

Hi technical team

i want to know the maximum power consumption of SN74LV4066APWR , would you please provide me with its value and the equation

also IS SN74CBTLV3245APWR'S MAXIMUM POWER CONSUMPTION=0.5W ?

These devices are passive switches. Just multiply the on-resistance with the current through the switch.

Hi Mandy,

Here's a good resource for how to solve for CMOS power consumption

[FAQ] How do I Calculate Power Consumption or Current Consumption for my CMOS Logic Device?

The capacitance will vary based on whether the switch is in the ON or OFF state. You would take the worst case value here, which would be the Cf + Cio.

Thanks,
Tyler
