DM74ALS05A Hex Inverter
with Open Collector Outputs
General Description
Features
This device contains six independent gates, each of which
performs the logic INVERT function. The open-collector outputs require external pull-up resistors for proper logical operation.

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.
