  • Hello, 

    Yes, you can connect OE directly to VCCA, and either power supply may be enabled first. The data sheet recommends grounding the OE pin while the power supplies are turning on so that the data pins are in a high impedance state, however this is to save power and the device will not be damaged by connecting OE to VCCA. I recommend the TXS App Note for more details on OE control.
