NSC DM5405W14B Dm5405/dm7405 hex inverters with open-collector output Datasheet

DM5405/DM7405 Hex Inverters
with Open-Collector Outputs
General Description
Pull-Up Resistor Equations
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.

Absolute Maximum Ratings (Note)
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.
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales
Office/Distributors for availability and specifications.
