    The I/O pins have internal pull-up resistors; the default state is high.

    To deactivate the I/Os during power up, keep OE low with a pull-down resistor and force it up later with a GPIO.

    Hi Allan,

    Please attempt the power sequencing pattern with OE low similar to Clemens' description. Let us know if you have any further concerns/ questions.
