Part Number: SN74CBTD1G125
Other Parts Discussed in Thread: TXS0102, LSF0102, SN74AVC2T245

Dear expert,

Did we have 2 channel switch with level shifting function integrated for UART interface?

The voltage of input UART is 3.3~5V, but only 1.8V acceptable at out put side.

Thanks.

Regards,

Ben

Hi Ben,

MSS does not have a switch that meets this request. I have changed the thread's responsibility to our Standard Logic team and they will be in touch soon.

Regards,

Kate

What do you mean with "input"/"output"? Doesn't an UART typically have one signal in each direction?

TXS0102 or LSF0102 have an enable pin.

Hi Ben,

Can you respond to Clemens, I also have the same confusion as him and would like to clear it up before making a part suggestion.

Hi Expert,

Sorry for this misunderstanding,

It's receiver side and transmitter side, did we have one chip solution?

The SN74AVC2T245 has two separate direction pins, but does not work with 5 V.

I would recommend the TXS0102.
