Note:
1. This value is for an SOP package (FP) and is based on actual measurements on a 40 × 40 × 1.6
mm glass epoxy circuit board. With a 10% wiring density, this value is permissible up to Ta =
45°C and should be derated by 8.3 mW/°C at higher temperatures. With a 30% wiring density,
this value is permissible up to Ta = 64°C and should be derated by 11.1 mW/°C at higher
temperatures.
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.
