Part Number: TXS0108E-Q1

Hi Expert:

  our customer is design TXS0108EQPWRQ1 level shift from 1.8V SoC I2C bus to 3.3V device I2C bus . we found there have ~0.5V voltage DC level on both 1.8V and 3.3V I2C bus line , the ~0.5V voltage DC level will disappear when remove TXS0108EQPWRQ1,  I attached customer design schematic (you can see page 1) and I2C CLK waveform( page 2) . I suspect the OE pin doesn't have pull down resistor causing the issue happened. could you please help review schematic and give comments about the schematic design ?
