† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 8: Voltage values are with respect to VSS.

NOTES: 9. All VSS pins should be routed to minimize inductance to system ground.
10. The algebraic convention, where the more negative (less positive) limit is designated as a minimum, is used for logic-voltage levels
only.
11. 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).
