DM7160 Magnitude Comparator

DM7160 Magnitude Comparator

June 1989

General Description

This device offers comparisons to determine equality be­tween two binary words. The DM7160 compares two six-bit
words. A strobe override is provided. When the strobe is
taken to a high logic level, the output is forced to a high
logic level. The device also features open-collector outputs
for expansion.

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.
