ELECTRICAL SPECIFICATIONS
Unless otherwise specified, the typical specification value applies over Vcc=5V, Vc=12V, VccLDO=5V and
T

=25°C. the Min and Max limits apply to the temperature range from 0 to 70°C. Low duty cycle pulse testing is
used which keeps junction and case temperatures equal to the ambient temperature.
