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.

1. This device series contains ESD protection and exceeds the following tests:

Human Body Model 2000 V per MIL−STD−883, Method 3015.

Machine Model Method 200 V.

2. Maximum power dissipation limits must be observed.

3. Tested junction temperature range for the MC33363B: Tlow = −25°C Thigh = +125°C

ELECTRICAL CHARACTERISTICS (VCC = 20 V, RT = 10 k, CT = 390 pF, CPin 8 = 1.0 mF, for typical values TJ = 25°C,

for min/max values TJ is the operating junction temperature range that applies (Note 3), unless otherwise noted.)
