Note: The ``Absolute Maximum Ratings'' are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the ``Electrical Characteristics'' table are not guaranteed at the absolute maximum ratings. The ``Recommended Operating Conditions'' table will define the conditions for actual device operation.

This DM74LS55 device contains a combination of AND-OR-INVERT functions. The internal gates are configured as two, four-input AND gates with their outputs connected to a two-input NOR gate.
