ADG3308 bidirectional, setting the direction

I am going to use the ADG3308 for level translation between 2.5 and 5V logic. I
see that there is no direction pin. Can individual bits go in one direction and
the other the opposite? Or do all the bits have to be going in the same


The ADG3308 is bidirectional and doesn't need any logic signal to set the
direction. One channel only will transmit in one direction at a given moment of
time. By applying a signal at A you will get the level translated signal at the
other end, Y. The same applies if you do it the other way round, Y to A.
