Electrical Characteristics
Unless otherwise specified, these specifications apply over the operating ambient temperature range of 0°C ≤ TA ≤ 70°C. TermPwr = 4.75V.
DISCONNECT: IMP5241 = LOW, DISCONNECT: IMP5242 = HIGH. Low duty cycle pulse testing techniques are used which maintain
junction and case temperatures equal to the ambient temperature.
