TXS0108E: TXS0108E and TXB0108 Problem

Part Number: TXS0108E

Tool/software:

Greetings,

We are currently haves modules featuring the TXB0108 and TXS0108 components within our hardware setup as depicted in the diagram provided. However, we are encountering certain issues with this configuration. Specifically, when MCU A triggers the TXB0108 to a low state, the 5V side of TXB and TXS fails to reach 0V entirely but instead stabilizes at around 4V. In scenarios where only a single device, such as MCU B and MCU A, is employed, the voltage on the 5V side stablizes to 1V. However, upon the addition of more devices, the voltage on the 5V side continues to escalate.
