SN74AVC4T245 / Thermal characteristic TJ (MAX) and power dissipation in package Pd

Hi

SN74AVC4T245 datasheet has the thermal information listed on page 5. Power dissipation should be calculated on customer's pcb.

The absolute maximum junction temperature is -40C to 150C.

Thanks

Hello, Jennifer Joseph~

I have one question for SN74AVC4T245PWR.
According to your answer as upper, absolute maximum junction temperature is -40'C to 150'C.
Is this temperature same for PWR (TSSOP-16) package or not??
If not, please let me know the operating junction temperature range of SN74AVC4T245PWR.

Thanks... C.W. :)

PS) In the datasheet, "Operating free-air temperature (Ta)" is -40'C to 85'C.

Hi C.W

Yes, it is applicable for TSSOP.

Please be advised it is ABS max junction temp only. We unfortunately cannot  spec an operating junction temp.

We could calculate operating junction based on thermal power dissipation  equation.  Thanks

Hello Jennifer.

Thanks for your answer.

How to calculate the operating junction temperature based on thermal power dissipation equation??
Or, where can I find the document for calculating the operating junction temperature??

Thanks... C.W. :)
