NOTES:

6. This specification applies when not in Auto-Zero phase.

7. Apply only when these pins are inputs, i.e., the mode pin is low, and the 7104 is not in handshake mode.

8. Apply only when these pins are outputs, i.e., the mode pin is high, or the 7104 is in handshake mode.

9. Clock circuit shown in Figures 14 and 15.

10. V+ must not be more positive than V++.
