Part Number: SN74LV1T34
Dear E2E member,
1. Does SN74LV1T34 can support TX for UART?
2. I study the datasheet and find the figure 2.
Why the VCC =3.3V but the output level under 3V?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Julian Chen:
If you make sure the fig.2 graph is not correct, I think that is OK to me.
Because my customer need to confirm it.
I cannot confirm that those graphs are incorrect because it doesn't mention what load the device is being operated on. The device is also being operated at a really fast speed of 50 MHz so that will also cause it to not reach 3.3 V.
To fully know how the device will output, you should look at the electrical characteristics section of the datasheet.
The VOH and VOL levels in these table provide you with the min and max levels of the output based on the current that is being driven. They can also be used to figure out how much drive strength the device has. As for the device working for UART. Yes the device will support UART communication but you cannot expect to operate at very fast speeds with a large load.
