TXS0108E: Level translator Low-Level input voltage

Part Number: TXS0108E

Recommended Operating Conditons Maximum Low-level input voltage for the A and B ports is 0.15V.  This is lower than most ICs guaranteed low-level output voltage.

Is the there a similar part that has a Vil closer to 0.4V or 0.5V?

  • Hi Amy,

    Please refer to the app note on factors affecting the Vol of the TXS device here :

    The Vol of the TXS is directly related to the input Vil. With input Vil at 0.4V, the output Vol will be slightly higher than that( depending on the Iol *Ron drop).

    You can have the input Vil at 0.4, but the electrical spec will not be guaranteed at the output across temp range.

  • I forgot to clarify something... the TXS family was originally chosen because I needed level translation for an I2C device, so the level-translator needs to be bi-directional and compatible with the I2C open-collector data line.

    The PDF attached to the response does not seem to address the TXS devices directly.  What page is relevant for Vil?

  • Hi Amy,

    TXS supports I2C interface. Here is the link to the app note: pg 2 -3 is relevant for TXS devices.
