NOTES:

4. The algebraic convention, where the more negative (less positive) limit is designated as a minimum, is used for logic-voltage levels

only.

5. Output current of 2 mA is sufficient to drive five low-power Schottky TTL loads or ten advanced low-power Schottky TTL loads (worst

case).

7. Logic pins include VDDL, EAD[7:0], EXLE, EALE, EOE, EDCLK, EDIO.
