TXS0206: Pull up/down resistor

Takashi Yamaguchi

Part Number: TXS0206

Hi team,

My customer is considering to use TXS0206. Could you answer to the question below?

When the voltage is applied to VCCA and no voltage is applied to EN and VCCB, will the output of B-side terminals (CLKB, CMDB, DATAB) become undefined or Hiz?

Customer would like to know if they need to put a resistor on the B-side terminal side to fix the logic at power-on.

Regards,

Yamaguchi

Wouldn't it be simpler to put a weak pull-down resistor on EN?

Hey Takashi,

I concur with Clemens on this, it makes more sense to add a pull-down on the EN otherwise you won't know the state of the I/O.
