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 D10 (VPP) of the HD4074459.
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
VCC 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 D0âD9, R0âR8, and R90âR92.
6. The maximum output current is the maximum current flowing out from VCC to each I/O pin.
7. Depends on the supply voltage.
