TI recommends that this current be limited to values under 1 mA for the TXS0108E. pulldown resistors must be avoided because of decreased VOH levels. If pulldown resistors are necessary they must be limited to values of 50 kΩ or greater. The negative impact of pulldown resistors on VOH levels also demonstrates why the TXS family of translators must only be used to drive high-impedance loads.
