2. The Current consumption characteristic will be different and the specified values can slightly change.
3. Leakage currents at pin 4 should be avoided. The bias shift of B_m caused by a leakage current I_L can be
calculated by: ∆B_m=(I_L × R_C(T))/S_C(T).
4. For higher ∆B the values may exceed the limits like following |∆B_m| < |0.05 × ∆B|
