DM5405/DM7405 Hex Inverters with Open-Collector Outputs

June 1989

General Description

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.

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.
