Notes: 1. Applies to D13 (VPP) of the HD407A4669.
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 D0–D3, R0–R4 and R6–RA.
6. Applies to D4, D5 and D9–D11
7. The maximum output current is the maximum current flowing out from VCC to each I/O pin.
8. Applies to D4, D5, D9–D11, R0–R4 and R6–RA.
9. Applies to D0–D3.
10. The operating temperature indicates the temperature range in which power can be supplied to
the LSI (voltage VCC shown in the electrical characteristics tables can be applied).
11. In the case of chips, the storage specification differs from that of the package products. Please
consult your Hitachi sales representative for details.
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.
