SN65LVDT14: Query on maximum junction temperature regarding

It's 150 °C; see [FAQ] What is the maximum junction temperature (TJMAX) for a device?

Hello,

The maximum junction temperature can be estimated by the equation: 

Tjmax= TAmax + (Pd x θJA), where TA is the operating free-air temperature and Pd is the power dissipation.

Here is a helpful example to go by: SN65LVDS31: Looking for max junction temp
