ELECTRICAL CHARACTERISTICS

(Unless otherwise specified, these specifications apply over the operating ambient temperature range of 0°C

≤ T

TermPwr = 4.75V.

For the LX5241/5243 DISCONNECT = L, for the LX5242 DISCONNECT = H. Low duty cycle pulse testing techniques are used which maintains junction and

case temperatures equal to the ambient temperature.)
