Hi TI team,

we are looking for a i2C mux , below is the application block diagram

With AEC qualified,
Temperature grade: -40°C ~ 85°C

Can you please suggest a suitable part? Can we use :TS5A23157QDGSRQ1 for below implementation?

Regards,

Hello Vidhya,

This part is suitable for your i2c application. For the following reasons

1.It is auto qualified and can operate at the required temperature range.

2.The bandwidth on this device is also high enough for i2c with typical applications being in the KHz range and this device can support up to 220Mhz.

3.Finally this device will only take up 17.5pf in capacitance which is less than 5% of your total allowable bus capacitance(400pf) in a i2c application.

Please let me know if you have any additional questions!
