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 D₁₃ (V_PP) of HD4074054 and HD4074094.
2. Applies to D₄ to D₇ of HD404092, HD404094, and HD4074094.
3. The total permissible input current is the total of input currents simultaneously flowing in from all
the I/O pins to GND.
4. The total permissible output current is the total of output currents simultaneously flowing out from
V_CC to all I/O pins.
5. The maximum input current is the maximum current flowing from each I/O pin to GND.
6. Applies to D₀–D₃, and R0–R4.
7. Applies to D₄–D₉ .
8. The maximum output current is the maximum current flowing out from V_CC to each I/O pin.
9. Applies to D₄–D₉ and R0–R4.
10. Applies to D₀–D₃.
