TXS0102: TXS0102: whether OE pin connect to high voltage (such as VCCA) when power up?

Part Number: TXS0102

Hi, team

in TXS0102 datasheet figure 13, it shows " Keep OE low until VCCA and VCCB are powered up"

but our customer want to connect the OE pin to high voltage (such as VCCA), could u help to confirm whether it's OK?

Thanks.

  • Section 10 of the datasheet says:

    To ensure the high-impedance state of the outputs during power up or power down, the OE input pin must be tied to GND through a pulldown resistor and must not be enabled until VCCA and VCCB are fully ramped and stable.

    If you do not care about the state of the outputs during power up, then you can connect OE directly to the power supply.
