SEMICONDUCTOR TECHNICAL DATA
4-Bit Magnitude Comparator
The MC14585B 4–Bit Magnitude Comparator is constructed with comple-
mentary 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 “less 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.
• Diode Protection on All Inputs
• Expandable
• Applicable to Binary or 8421–BCD Code
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load over the Rated Temperature Range
ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎΕ Can be Cascaded – See Fig. 3
