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 the HD4074344 and HD4074394.
2. Applies to the following pins.
HD404344R series and HD4074344: D₀–D₅, R0, R1, R2, R3
HD404394 series:
D₀–D₅, R0, R1₃, R2, R3₁–R3₃
3. Applies to the following pins.
HD404394 series:
R1₀–R1₂
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 D₁, D₂, R1, and R2.
8. Applies to the following pins.
HD404344R series and HD4074344: D₀, D₃–D₅, R0, R3
HD404394 series:
D₀, D₃–D₅, R0, R3₁–R3₃
9. The maximum output current is the maximum current flowing out from V_CC to each I/O pin.
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.
