An output enable input (OE) is used to disable the device. Setting OE = LOW causes all

become disabled. The enable time (t

high-impedance OFF-state during power-up or power-down, pin OE should be tied to
GND through a pull-down resistor, the minimum value of the resistor is determined by the
current-sourcing capability of the driver.
As mentioned previously the NTB0102 is designed with low static drive strength to drive
capacitive loads of up to 70 pF. To avoid output contention issues, any pull-up or
pull-down resistors used must be above 50 k. For this reason the NTB0102 is not
recommended for use in open drain driver applications such as 1-Wire or I
these applications, the NTS0102 level translator is recommended.
