ISL705ARH Datasheet, PDF (9/15 Pages) Intersil Corporation – Rad-Hard, 5.0V/3.3V μ-Processor Supervisory Circuits

ISL705ARH, ISL705BRH, ISL705CRH, ISL706ARH, ISL706BRH, ISL706CRH
Post Radiation Characteristics Unless otherwise specified, V_DD = 4.75V to 5.5V for the ISL705ARH/BRH/CRH, V_DD = 3.15V to 3.6V
for the ISL706ARH/BRH/CRH T_A = +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.
