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 pin TEST (V_PP) of HD4074339.
2. Applies to all standard voltage pins.
3. Applies to high-voltage pins.
4. The total permissible input current is the total of input currents simultaneously flowing in from all
the I/O pins to GND.
5. The total permissible output current is the total of output currents simultaneously flowing out from
V_CC to all I/O pins.
6. The maximum input current is the maximum current flowing from each I/O pin to GND.
7. Applies to ports R3, R4, and R5.
8. Applies to ports R0, R6, and R7.
9. Applies to ports R0 and R3 to R7.
10. The maximum output current is the maximum current flowing from V_CC to each I/O pin.
11. Applies to ports D₀–D₁₃, R1, R2, R8, and R9.
