Part Number:SN74LV1T08
Hello,
I am planning to use part from LV1T logic family (assume PN SN74LV1T08) for my design. I have a condition during which Vcc of the part is not powered but the A and B inputs are getting 3.3V and 5V signals from a different logic IC. I would like to know the following:
1. Is it okay to send the signals to A and B inputs when Vcc is not powered? By okay I mean to ask if the SN74LV1T08 will not get damaged or the Vcc pin will not backfeed.
2. If it is okay, how do I infer this information from the datasheet?
3. Also I assume that Vin pins are tri-stated or are in high impedance mode during Vcc = 0V.
Thank you
