NSC DM9324W-883, DM9324J-883 Datasheet
TL/F/9792
9324/DM9324 5-Bit Comparator
June 1989
9324/DM9324 5-Bit Comparator
General Description
The 9324 expandable comparators provide comparison between two 5-bit words and give three outputsБ‘less than’’,
‘‘greater than’’ and ‘‘equal to’’. A HIGH on the active LOW
Enable Input forces all three outputs LOW.

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.
