Can xOE have an input signal (High) before Vcc gets powered?
Taken from the DS:
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
It states during power-up we need to ensure the high-impedance state. Another way to do this, is to apply xOE before Vcc, keeping the device in high-impedance.
The ABS MAX section in the DS for Vo states a voltage can be applied to the outputs when device is in powered-off state. Does that apply for xOE as well?
