CD4585B CMOS 4 位幅度比较器

CD4585B 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 CD4585B 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 systems designers to expand the comparator function to 8, 12, 16.....4N bits. When a single CD4585B 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 Fig
