CD4585BMS 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. The CD4585BMS has eight comparing inputs (A3, B3, through A0, B0), three outputs (A < B, = 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 CD4585BMS 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 Figure 9. The CD4585BMS is supplied in these 16-lead outline packages: Braze Seal DIP H4T Frit Seal DIP H1E Ceramic Flatpack H6W
