DM5406/DM7406 Hex Inverting Buffers with High Voltage Open-Collector Outputs
June 1989
DM5406/DM7406 Hex Inverting Buffers with
High Voltage Open-Collector Outputs
General Description
This device contains six independent buffers 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.
