Hello,

i wanted to ask if there is any Level-Shifter with Enable-Pin as well as with DIR-PIN?



On the Datasheet is written that the VREF-A and B should have a value between 1.2 V to 3.6 V. My second Question is: how could I disable the levelshifter ? should the VREF-A and VREF-B set to 0 V at the same time? or could i set VREF-A firstly to zero without getting some unwanted signals on the output lines?

Thank You
