Part Number: TLC374

Hi,

Good day.

Our customer is looking for the TJmax for the TLC374. Can you please help us provide this parameter? Thank you.


Regards,

    Hi Cedrick,

    the answer can be seen at two points of the datasheet.

    1. Form the "absolute maximum ratings". The maximum storage temperature is 150°C. This is your maximum junction temperature, as storiging is usually down without powering the chip Relaxed

    2. From the "dissipation rating table". For the D package the power rating is 7.6mV/°C above 84°C and the specified maximum power at 125°C is 190mW. So no power must be dissipated at 190mW / 7.6mV x °C + 125°C = 150°C. This again is your maximum junction temperature.
