Post High Dose Rate Radiation Characteristics (V± = ±15V) Unless otherwise
specified, V± = ±15V, VCM = 0, VO = 0V, TA = +25°C. This data is typical mean test data post radiation exposure at a high dose 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.
