TXS0104E: Replace TXB0104 with TXS0104

Jim CHEN

Part Number: TXS0104E
Other Parts Discussed in Thread: TXB0104

Dear Team,

At first, we used TXB0104 on I2C application. The I2C signal cannot work normally.

We went to checked the spec and found that TXB0104 datasheet has been updated recently, and it said that TXB0104 cannot be used on I2C application.

Therefore, could you help to review below schematic if we can replace TXB0104 with TXS0104 directly or not?

Thank you.

Hi Jim,
I hve asked our translation expert to take a look for you.

Hi Jim Chen,

TXS is recommended for open drain signals and can replace TXB being P2P. TXS also have the internal 10k resistor.

So, the external resistor on the schematic is not required anymore. It is also recommended to grnd the unused IO ports as well.

You can also refer to the translation FAQs for TXS and TXB refers to the signal interface suitable for each device.
