SN74avc32t245 - what is internal state of OE?

Hi All,

We have discovered a potential oops on a board that is getting ready to run down the line.

 If you can help me get a quick answer that would be great….

 Part SN74avc32t245   - issue is that we left one OE [output enable] floating.  I seems to state in the datasheet on page 1 that;

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.

 

Which leads me to think OE is always pulled low internal, which would be fine for our application….

 

Can you point me, or send this in the right direction to confirm / verify the real internal condition?

 

Thanks! Luke
