Input SOIC−8* D SUFFIX CASE 751 SOT−89 CASE 528AG *SOIC−8 is an internally modified SO−8 package. Pins 2, 3, 6, and 7 are electrically common to the die attach flag. This internal lead frame modification decreases package thermal resistance and increases power dissipation capability when appropriately mounted on a printed circuit board.
