Notes: 1. Applies to the HD4074318 TEST (V
PP) pin.
2. Applies to all standard pins.
3. Applies to high voltage pins.
4. The allowable total input current is the sum of the currents flowing from all the I/O pins
to ground at the same time.
5. The allowable total output current is the sum of the currents flowing from V
CC to all the
I/O pins at the same time.
6. The allowable input current is the maximum value of the currents flowing from each I/O
pin to ground.
7. Applies to R3 and R4.
8. Applies to R0.
9. Applies to R0, R3, and R4.
10. The allowable output current is the maximum value of the currents flowing from V
CC to
each I/O pin.
11. Applies to D
0 to D8, R1, R2, and R8.
Use of this LSI at levels that exceed the absolute maximum ratings can permanently
damage the LSI. Also note that it is desirable to use this LSI within the conditions specified
in the “Electrical Characteristics” section during normal operation. Exceeding those
conditions can cause the LSI to operate incorrectly and may adversely affect LSI reliability.
