SN74LVC32A: Tjmax spec

Hello

Thanks, the answer for this question is as below, but my customer uses these logic devices without the datasheet rated values, such as the ambient temperature is higher than 85C. Customer think the power comsuption of the logic devices should be very low, and when the ambient temperature over spec, maybe it also within Tjmax, so our part can also work. Do you know what are the Tjmax of these two devices for long time work?



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.
