I have the following requirement in my design
Note: OD drives 3.3V IOs also
I found 3 options for the same.
TXS0108E, TXB0104, sn74lvc8t245.
My voltage high/low req. is
3.3V:
VOH/L - 2.94V/0.4V
VIH/L - 2V/0.8V
1.8V:
VOH/L - 1.26V/0.45V
VIH/L - 1.2V/0.4V
TXS0108E does not seem to match the voltage requirements.
sn74lvc8t245 seems fine but uses dir pins and is an 8-bit translator.
I am thinking of using TXB0104 for the same.
However, in TXB0104 datasheet, it is mentioned that it is not recommended for open drain voltage translations (Bi-directional IOs).
1) Can I use TXB0104 for my design?
2) If it is possible, in our scenario, 3.3V pins are software configurable. On start-up, pins may act as I/Ps. Will this cause any issues?
3) If not, can you suggest some alternatives?
