MM54C85/MM74C85 4-Bit Magnitude Comparator
General Description
The MM54C85/MM74C85 is a four-bit magnitude compara-
tor which will perform comparison of straight binary or BCD
codes. The circuit consists of eight comparing inputs (A0,
A1, A2, A3, B0, B1, B2, B3), three cascading inputs (A
l
B,
A
k
B and A
e
B), and three outputs (A
l
B, A
k
B and
A
e
B). This device compares two four-bit words (A and B)
and determines whether they are ‘‘greater than,’’ ‘‘less
than,’’ or ‘‘equal to’’ each other by a high level on the appro-
priate output. For words greater than four-bits, units can be
cascaded by connecting the outputs (A
l
B, A
k
B, and
A
e
B) of the least significant stage to the cascade inputs
(A
l
B, A
k
B and A
e
B) of the next-significant stage. In
addition the least significant stage must have a high level
voltage (V
IN(1)
) applied to the A
e
B input and low level
voltage (V
IN(0)
) applied to A
l
B and A
k
B inputs.
