Hello,

I am looking for a bi-directional level translator that has V_CCA of 1.8V and V_CCB of 3.3V OR 1.8V. 

The IO voltage is 1.8V and some applications require 3.3V. I am looking to have a single solution to toggle between maintaining the 1.8V IO voltage or shifting to 3.3V IO voltage.

The IO have speeds up to 50MHz.

Please let me know what is the best solution.

Regards,

Erik

    Hi Erik,

    If by bi-direction you mean the same device with multiple channels going opposite direction, please see the TXU family (TXU0304 for example), the AXC family (SN74AXC4T774 for example) or the TXV family (TXV0108 with DIR pin to control direction from A to B or B to A).

    If by bi-direction you mean a channel can go both ways, please see TXB0304, thanks.

    Best Regards,

    Michael.
