Stresses above those l isted under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated n  perational sections of this specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect evice reliability.

In the HCC/HCF4585B  series, the HCC4585B(extended temperature range) and HCF4585B (intermediate temperature range) are monolithic integrated circuits, available in 16-lead dual in-line plastic or ceramic package, and plastic micropackage. The HCC/HCF4585B is a4-bitmag-nitudecomparator designed for usein computer and logic applications that require thecomparison of two 4-bit words. This logic circuit determines whether one 4-bit word (Binary or BCD) is "less than", "equal to", or "greater than" a second 4-bit word. The HCC/HCF4585B  have eight comparing inputs (A3,B3, through A0, B0), three outputs (A< B, A= B, A>B) and three cascading inputs (A < B, A = B, A > B)that permit systems designers to expand the com-parator function to 8, 12, 16 ... 4 N bits. When a single HCC/HCF4585B is used, the cascading in-puts are connected as follows : (A < B) = low,(A =B) = high, (A> B) = high. Cascading these units for comparison of more than 4 bits is accomplished as shown in typical application.
