† _{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, and all VSS pins should be routed so as to minimize inductance to system ground.

NOTES: 9. The algebraic convention, where the more negative (less positive) limit is designated as a minimum, is used for logic-voltage levels
only.
10. 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).
