93L24
5-Bit Comparator

93L24 5-Bit Comparator

June 1989

General Description

The 93L24 expandable comparator provides comparison
between two 5-bit words and gives three outputsБ‘less
than’’, ‘‘greater than’’ and ‘‘equal to’’. A HIGH on the active
LOW Enable Input forces all three outputs LOW.

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.
