Partial power-down of 74LVC1G66 analog switch

Bob Dvorak

Does the 74LVC1G66 support partial power down operation? In my application, 5V would be applied to the outputs when the device is powered down. Would current flow into the outputs during this condition?

Thank you!

Hi Bob

Unfortunately this device will not allow you to go above Vcc.

You might take a look at this part. It has the Ioff feature that would allow this. http://focus.ti.com/lit/ds/symlink/sn74cbtlv1g125.pdf
