4?Bit Magnitude Comparator

The MC14585B 4?Bit Magnitude Comparator is constructed with complementary MOS (CMOS) enhancement mode devices. The circuit has eight comparing inputs (A3, B3, A2, B2, A1, B1, A0, B0), three cascading inputs (A B), and three outputs (A B). This device compares two 4?bit words (A and B) and determines whether they are “l(fā)ess than”, “equal to”, or “greater than” by a high level on the appropriate output. For words greater than

4?bits, units can be cascaded by connecting outputs (A > B), (A B) on the least significant (first) comparator are connected to a low, a high, and a low, respectively.

Applications include logic in CPU’s, correction and/or detection of instrumentation conditions, comparator in testers, converters, and controls.
