Note:
1. This value is based on actual measurements on a 40 × 40 × 1.6 mm glass epoxy circuit board.
At a wiring density of 10%, it is the permissible value up to Ta = 45°C, but at higher temperatures
this value should be derated by 8.3 mW/°C. At a wiring density of 30% it is the permissible value
up to Ta = 64°C, but at higher temperatures it should be derated by 11.1 mW/°C.
2. For the DILP package.
This value applies up to Ta = 45°C; at temperatures above this, 8.3 mW/°C derating should be
applied.
