Other Parts Discussed in Thread: SN74LVC2G34, TXU0202
Hi,
A my account plans to use TXS0102 for UART signal isolation with both VCCA and VCCB are 3v3. Is TXS0102 suitable for this application? if yes, pls kindly help check the schematic

Hi Ken,
The TXS0102 can be used to put the I/Os in high-Z when OE is driven low or if VCCA/VCCB is turned off and at 0V. This feature is denoted by IOFF in the datasheet. Note that this device will not redrive your signals similar to what Clemens has mentioned (you may need an I2C buffer instead for that). Please also reference to this app note for further recommendations across different comm. protocols:
