MM74C85
4-Bit Magnitude Comparator
General Description
The MM74C85 is a four-bit magnitude comparator 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
>
B, A
<
B
and A
=
B), and three outputs (A
>
B, A
<
B and A
=
B).
This device compares two four-bit words (A and B) and
determines whether they are “greater than,” “l(fā)ess than,” or
“equal to” each other by a high level on the appropriate out-
put. For words greater than four-bits, units can be cas-
caded by connecting the outputs (A
>
B, A
<
B, and A
=
B)
of the least significant stage to the cascade inputs (A
>
B, A
<
B and A
=
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
=
B input and low level voltage
(V
IN(0)
) applied to A
>
B and A
<
B inputs.
