Part Number: TXB0104-Q1
Other Parts Discussed in Thread: LSF0204-Q1, TXS0104E-Q1

I need a level translator which translates from 3.3V-1.8V (vice-versa also). Please suggest a suitable Level translator.

Hi Abhishek,

There are multiple translators that can fit this use case. If the signals are push-pull driver based and fixed direction signals per channel, the TXU0x04-Q1 would work here. However, if open drain driver based, then TXS0104E-Q1/ LSF0204-Q1 should be used instead.

Regards,
Jack

I need it for UART section. So is it suitable for UART also?

Abhishek,

Yes.

Here is an app note for level shifting UART signals in more detail: https://www.ti.com/lit/ab/scea095b/scea095b.pdf?ts=1764016175162&ref_url=https%253A%252F%252Fwww.google.com%252F
