SN74AUP2G126: System with Vcc = 0 with 1OE and 2OE still supplying voltage

Part Number: SN74AUP2G126


Hi, I'm working with a customer that is trying to use this device in their system. In their application (at random times) they are setting Vcc = 0 with the 1OE and 2OE pins still receiving a voltage, my question is: Does this cause problems within the device?

My concern is that if I'm not powering the device but I'm supplying voltage to the enable pins that it will damage the device.
