TXB0108 OE pin has internal Pull down resistor ?

No; if OE needs to be pulled down, you need an external resistor (as shown in figure 9-1 and section 11.2).

These schematics show an external pulldown.

Thank you Clemens / Dilip.

In current design. I don't have option for external pull-down. Only option for Pull-Up is available. I need to disable the device. Hence, I was checking whether the device do have a internal pull-down.

The only way to disable the TXB is to pull OE low, or to force V_CCA or V_CCB to 0 V.
