technical inquiry on TXS0108EPWR

Hello Goutham,

The recommended specifications are shown below. Functional operation of the device beyond these conditions is not implied.

Hello Sharma,

Welcome to TI's E2E forum.  This forum was design to share knowledge between engineers and to be a place to get questions answered.  Usually the questions or concerns about a product are either covered in the datasheet, in an application note, or in a previous E2E post. 

One way to use E2E is to literally type the question into the search bar above.  As you see below I typed in "maximum acceptable junction temp" and found the following posts.  Clicking on the post not only showed what is included on the datasheet but gave additional application information that which give insight on the part in its application. 

Here is the link to the thread that answers your questions.

Hello Sharma,

Power dissipation in the part is a function of VCC, Load Capacitance (capacitance at pin due to traces and other devices connected to that node), operating frequency, rise/fall times, and other internal parasitic's of the part.  

We have a wonderful app note that goes through the process of calculating your power dissipation in your specific application.  Here is the link:

I have even taken the liberty to post the Cpd values of the TXS0108E so you don't have to look it up in the datasheet. See below:

Let us know if you have questions about how to do the calculations or if something doesn't make sense.  We would  be more than happy to explain anything that isn't clear. 

If you are new to using these type of logic parts may I suggest reading, "Understanding and Interpreting Standard-Logic Data Sheets"

This was very insightful when I was first learning about these types of parts.

Sincerely,
