Notes: Permanent damage may occur if these absolute maximum ratings are exceeded. Normal operation
must be under the conditions stated in the Electrical Characteristics table. If these conditions are
exceeded, the LSI may malfunction or its reliability may be affected.
1. D₁₀ (V_PP) of the HD4074329 and HD4074329U.
2. The total permissible input current is the total of input currents simultaneously flowing in from all
the I/O pins to ground.
3. The total permissible output current is the total of output currents simultaneously flowing out from
V_CC to all I/O pins.
4. The maximum input current is the maximum current flowing from any I/O pin to ground.
5. Applies to D₈, R0–R5.
6. Applies to D₀–D₇.
7. The maximum output current is the maximum current flowing from V_CC to any I/O pin.
8. Applies to D₀–D₈, R0–R5.
