TH04 PD Power Dissipation — W PD = P
INTERNAL + PI/O
TH05 PINTERNAL Internal Power Dissipation — W PINTERNAL = IDD x VDD
(1)
TH06 PI/O I/O Power Dissipation — W PI/O =  (IOL * VOL) +  (IOH * (VDD - VOH))
TH07 P
DER Derated Power — W PDER = PDMAX (TJ - TA)/JA

Note 1: IDD is current to run the chip alone without driving any load on the output pins.
2: TA = Ambient Temperature, TJ = Junction Temperature.
