Notes: Permanent damage may occur if these 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 the HD4074889, HD4074899, and HD4074869 TEST (VPP) pin.
2. The allowable input current (total) is the sum of all currents flowing from I/O pins to ground at the
same time.
3. The allowable output current (total) is the sum of all currents flowing from VCC to I/O pins.
4. The allowable input current (per pin) is the maximum current allowed to flow from any one I/O pin
to ground.
5. Applies to pins D0 to D3 and R0 to R8.
6. Applies to pins D4 to D11.
7. The allowable output current (per pin) is the maximum current allowed to flow from VCC to any
one I/O pin.
8. Applies to pins D4 to D11 and R0 to R8.
9. Applies to pins D0 to 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.
