DM5407/DM7407 Hex Buffers with High Voltage Open-Collector Outputs

June 1989

DM5407/DM7407 Hex Buffers with
High Voltage Open-Collector Outputs

General Description

This device contains six independent gates each of which
performs a buffer 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.
