I understand the CB3T family can do 5V to 3.3V level shifter as well as 2:1 mux.
But when we up drive 3.3V to 5V, do we just add pullup on the 5V side?
B1 -3.3V input
B2 - 5V input
A - 5V output <= Need pullup?
Thanks,
Khoi

Hi Khoi,
I am providing a link to our of our appnotes which talks about the CB3T family. It has an example of how to connect it for translation.
Figure 35 shows the use of resistors for translating from low to high.
I hope this helps!
