Part Number: SN74HC161

Hi All,

My customer need to know junction temperature(Tj) for SN74HC161DR.

It haven't parameter from datasheet.

Could you please help to provide this data to us??

    Hi,

    In the FAQ page for this forum we actually have a very thorough answer for this. 

    The vast majority of logic devices do not list a maximum junction temperature (TJ(max)) on the datasheet.

    For logic devices, TJ(max) is equal to the maximum storage temperature (Tstg(max)) as listed in the Absolute Maximum Ratings table of the datasheet unless otherwise specified.

    It is extremely unlikely for any logic device to ever reach its maximum junction temperature while being operated within the datasheet rated values.  I will keep this short, but suffice it to say that if you operate a logic device at its maximum datasheet ratings for ambient temperature and output power, the junction temperature will likely still be far below the maximum allowable value.  If you are interested in learning more about power dissipation in logic devices, please read our application report entitled CMOS Power Consumption and Cpd Calculation.

    Regards,
