Hi AE,

       The EC Pin include internal pull up 400k.

       Please provide me some suggestion to control output EN Pin under the conditions.

       Output EN Pin provide  0V :           Tx / Rx channels will be Enable / disabled ?

       Output EN Pin provide  3.3V :        Tx / Rx channels will be Enable / disabled ?

       Output EN Pin setting   floating :    Tx / Rx channels will be Enable / disabled ?

Best Regards

Bruce

    EN is an input pin, and not an output pin. You can drive EN pin

    When EN pin is being driven low, TUSB1002A will be in shutdown mode. When in shutdown, TUSB1002A’s receiver terminations will be high impedance and tx/rx channels will be disabled.

    When EN pin is being drive high or floating, TUSB1002A will in normal mode.

    Thanks
