SN74LVC1G32-Q1: output in case of disconnected supply

Amr Elhadidy

Part Number: SN74LVC1G32-Q1

Hi,

I use a 3.3V supply from a buck converter to supply the OR-Gate. May I ask you please, in case of Zero Input voltage to buck or Floating Input of the buck, what would the Output of the OR-Gate in this case? will it be tied to some pull-up or to some pull-down resistor? or Floating?

Thank you

Hi Amr,

In the case of 0V input or Floating input to the supply of the SN74LVC1G32-Q1, the inputs and outputs enter a high impedance state. You can read more about this high impedence state (called Partial Power Down) in this FAQ.

Thanks!
