ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperature range of 0°C ≤ TA ≤ 70°C. TermPwr = 4.75V,
DISCONNECT A or B = L. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
