(1) All hot and cold limits are specified by correlating the electrical characteristics to process and temperature variations and applying statistical process control.

(2) The junction temperature (T_J in °C) is calculated from the ambient temperature (T_A in °C) and power dissipation (P_D in Watts) as follows: T_J = T_A + (P_D × R_θJA) where R_θJA (in °C/W) is the package thermal impedance provided in Section 6.4.
