Hello,

I am using the a level shifter. In my applecation OE-PIN should be tied to VCCA (Low-level). Do I need to use a pulldown resistors between the VCCA and OE-PIN? if yeah should the R_PD value be minimum 50 Kohm or is the minimum value of the R_PD determined by the current-sourcing capability of the driver?

Thanks in Advance.

OE is a high-impedance CMOS input, so this pin itself does not need a pull-down resistor.

You need a pull-down resistor only if the OE pin should be low during power-up, and then needs to be forced high later with a GPIO output from the microcontroller.

Thank you for your replay.
My last question is: Can the channels be operated independently in different directions at the same time (for example channel 1 from A to B and at the same time channel 2 from B to A)?

Yes, the channels are independent.
