TMUX136: what’s the Recommend Operation Temperature and Recommend Junction Temperature?

Hi Adam,

Thank you for your question. Check out the information in this E2E post: https://e2e.ti.com/support/switches-multiplexers/f/388/t/167939

It mentions the app note Semiconductor and IC Package Thermal Metrics, which explains how the thermal measurements are made and how to calculate junction temperature. The post even provides a calculator to find junction temperature: 6355.Signal Switch power dissipation and junction temperature calculator.xlsx

I have filled in the max specifications in the calculator from the TMUX136 datasheet already. This calculator uses the following formula:

Tjmax= Ambient Tempmax + Pmax(RθJA) 

The recommended operating temperature is TA, operating free-air temperature (-40C to 85C).

Let me know if this helps!

Regards,

Kate
