9 / 19 page  ISL705AEH, ISL705BEH, ISL705CEH, ISL706AEH, ISL706BEH, ISL706CEH 9 FN8262.0 March 30, 2012 Post Radiation Characteristics Unless otherwise specified, VDD = 4.75V to 5.5V for the ISL705AEH/BEH/CEH, VDD = 3.15V to 3.6V for the ISL706AEH/BEH/CEH TA = +25°C. This data is parameter deltas post radiation exposure at a rate of 50 to 300rad(Si)/s. This data is intended to show typical parameter shifts due to high dose rate radiation. These are not limits nor are they guaranteed.
