Part Number: SN74AVCH4T245

Hello E2E,

What is the max junction temperature rated for on the SN74AVCH4T245?

Thank you very much!

    Hello Russell,

    We do not guarantee a Maximum Junction Temperature (the hottest temperature of the silicon chip inside the package) within the datasheet because it will change based on many factors such as:

    1. PCB design

    2. Altitude

    3. External ambient temperature

    4. Power dissipation

    What we can provide is the Absolute Maximum Junction Temperature (the temperature beyond which damage occurs to the device). For the SN74AVCH4T245, this is 150C.

    This app note provides the details: www.ti.com/.../spra953c.pdf

    Since the SN74AVCH4T245 power dissipation is in the uW range, the maximum junction temperature for these devices will be well below the Absolute Maximum Junction Temperature.
