Notes: Permanent damage may occur if these absolute maximum ratings are exceeded. Normal
operation must be under the conditions stated in the electrical characteristics tables. If these
conditions are exceeded, the LSI may malfunction or its reliability may be affected.
1. Applies to D₁₁ (V_PP) of the HD4074629.
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 each I/O pin to ground.
5. Applies to R0–R7.
6. Applies to D₀–D₉.
7. The maximum output current is the maximum current flowing out from V_CC to each I/O pin.
8. Applies to D₀–D₉ and R0–R7.
