SN74AUP1T34: Down Shifting Possible?

Part Number: SN74AUP1T34
Other Parts Discussed in Thread: 2N7001T

Hello,

I was wondering if this part would allow you to go down in voltage as well as up.  The datasheet only mentions going up in voltage and I would like to go down to 1.8V from 3.3V.

Thanks,

Robert

    Hi Robert,

    Yes, this device can do up and down level translation depending on the output Vcc voltage level.

    In your case, the Vcca = 3.3V and Vccb = 1.8V.

    You could also consider using 2N7001T for unidirectional level translation.

    If there are multiple bits in your application, let me know and we can suggest other devices suitable for you.
