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, A = B, and A > B), and three outputs (A
< B, A = B, and 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),
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.

2. Maximum Ratings are those values beyond which damage to the device
may occur.
3. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/ C From 65 C To 125 C
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
high–impedance circuit. For proper operation, V

and V

should be constrained
to the range V

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V
SS
or V
DD
). Unused outputs must be left open.
