Hi,

     I am using TXB0108 in my design. It is specified that TXB0108 has very "low dc drive strength", but not given exactly the values of IOH & IOL.

Can anyone tell me what is the "dc drive strength" supported by TXB0108.

Also is there any bidirectional voltage translator (auto direction sensing) with higher "dc drive strength".

 

Thanks & Regards,

Rahul.

    Hi Rahul.

    When the output of the device is in a steady high or low state, it is exclusively driven by the 4k Ohm impedance buffer.

    This device works best in applications with less than 70pF loading, and with high load resistance.

    The only other option at this point for auto-direction sensing translators are the TXS devices. These have no independent DC low drive, the low state is controlled by the active external driver. On the high state they are driven by the internal pull-up resistors.

    The direction controlled translators have higher drive strengths.

    Regards,

    Hattie
