Other Parts Discussed in Thread: CD74HC4075, , SN74HC86
I understood logic's Tj(max) will be typically 150℃ unless otherwise specified in datasheet from following E2E link.
Just want to double-check with you.
Is it correct that all SN74HC257, CD74HC4075 and SN74HC86 have 150℃ Tj(max)? Thanks.
Customer want to compare the maximum power dissipation to other company's logic, so they are trying to use "Pd=（Tj(max)-TA）/θJA" to calculate maximum power dissipation.
Please also let me know if this formula is not correct.
"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. This value is typically 150°C."
