TH03 T
JMAX Maximum Junction Temperature 150 °C
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 = Σ (IOL * VOL) + Σ (IOH * (VDD - VOH))
TH07 P
DER Derated Power — W PDER = PDMAX (TJ - TA)/θJA
