HCF4585B is a 4-bit magnitude comparator designed for use in computer and logic applications that require the comparison 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. HCF4585B has 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 system designers to expand the comparator function to 8, 12, 16...4N bits. When a single HCF4585B is used, the cascading inputs 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.
