SN65LVDS387: Thermal Data Required

Part Number: SN65LVDS387

Hi Team,

May I ask for help? Our customer have concerns below:

"I need to Perform the Thermal Analysis for  SN65LVDS387DGG, Kindly request you to provide Below Thermal Data.

1.Maximum operating Temperature.

2.Junction to case resistance.(RjC)

3.Junction to Base Resistance(Rjb)"

For number 1 concern, I was able to check in datasheet that recommended Maximum operating Temperature is 85°C. But for number 2 and 3 concern. Can you please provide this details to us? Thank you so much in advance.

Kind regards,
Gerald
