TXS0206: TXS0206 signal driving strength

Hi Jefer,
I would recommend using a buffer such as SN74LVC244A or SN74LVC1G34 to increase the line's drive strength if possible. TXS is not exactly a buffered device. Whatever device is driving it low will also be driving the line on the other side of it, and when it goes 'high' the output is essentially high-impedance and the pull-up does most of the work (there is also a one-shot edge accelerator that helps speed up the transition from low to high).

If you can't use a buffer due to directionality (ie signals that change direction without warning), you can minimize the impact of parasitic capacitance from the long trace by placing the TXS device as close as possible to the higher-voltage device (usually the SD card).
