† 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 6: Voltage values are with respect to VSS.

† The minimum level specified is a result of the manufacturing test environment. This signal has been characterized to a minimum level of
2.4 V over the full temperature range.
‡ The maximum level specified is a result of the manufacturing test environment. This signal has been characterized to a maximum level of
0.8 V over the full temperature range.
NOTES: 7. All VSS pins should be routed to minimize inductance to system ground.
8. The algebraic convention, where the more negative (less positive) limit is designated as a minimum, is used in this data sheet for
logic voltage levels only.
9. 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).
