SN74LVC1G126: OE when VDD is powered off scenario

Other Parts Discussed in Thread: SN74LVC244A

Hi Team,

Quick question on the SN74LVC1G126.

If the OE pin is driven by biased 3.3V when VDD is powered off, is there any potential damage to the chip? I have the same question for the SN74LVC244A, but this is slightly different because OE is active low.

Appreciate the help!

Thank you,
Delaney

This is allowed; see [FAQ] Can the input voltage (Vi) to my logic device be higher than the supply voltage (Vcc)?
