Post Radiation Characteristics Unless otherwise specified, VDD = 4.75V to 5.5V for the ISL705ARH/BRH/CRH, VDD = 3.15V to 3.6V
for the ISL706ARH/BRH/CRH 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 radiation. These are not limits nor are they guaranteed.
