Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
ELECTRICAL CHARACTERISTICS (VCC = 15 V, RT = 3.65 kW, CT = 1.0 nF, for typical values TA = + 25°C, for min/max values TA
is the operating ambient temperature range that applies [Note 2], unless otherwise noted.)

1. Maximum package power dissipation limits must be observed.
2. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
Tlow = 0°C for MC34025
Thigh = +70°C for MC34025
Tlow = − 40°C for MC33025
Thigh = +105°C for MC33025
