4Bit Magnitude Comparator
The MC14585B 4Bit 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, A = B, and A > B), and three outputs (A < B,
A = B, and A > B). This device compares two 4bit 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
4bits, units can be cascaded by connecting outputs (A > B), (A < B),
and (A = B) to the corresponding inputs of the next significant
comparator. Inputs (A < B), (A = B), and (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.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
highimpedance circuit. For proper operation, V

Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V

or V

). Unused outputs must be left open.
