Hello,
 
Our customer would like to use one buffer IC for both signals of HPD and CBUS.
Then, I think that SN74AUP1G07 may be used as buffer IC of  these signals by one device.
 
Can SN74AUP1G07 as buffer IC for HPD and CBUS signal?
Please see the attached file as our image.

  • You are showing the signal going both directions. The LVC2G07 will only go one direction.

    Can you give me the details of both signals

    input and output levels on each signal and input and output levels when going back the other direction.

    Would a switch work here or does it need to be a Buffer?

    We do not have a duel buffer that can do both. However they could use a single buffer for each application.

    For 5V single direction they can use SN74LVC1G240 or SN74LVC1G34

    for 1.8V both direction they might use SN74LVC1T45 or the TXB0101.
