DESCRIPTION
The HCF4063B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
The HCF4063B is a low power 4-bit magnitude
comparator designed for use in computer and
logic applications that require the comparison of
two 4-bit words. This logic circuit determines
whether one 4-bit word (Binary or BCD) is "less
than", "equal to" or "greater than" a second 4 bit
word. The HCF4063B has eight comparing inputs
(A3, B3 through A0, B0), three outputs (A<B, A=B,
A>B) and three cascading inputs (A<B, A=B, A>B)
that permit system s designers to expand the
comparator function to 8, 12, 16...4N bits. When a
single HCF4063B is used the cascading inputs
are connected as follows :
(A<B) = low, (A=B) = high, (A>B) = low.
For words longer than 4 bits, HCF4063B device
may be cascaded by connecting the outputs of the
less-significant comparator to the corresponding
cascading inputs of the more significant
comparator. Cascading inputs (A<B, A=B, and
A>B) on the least significant comparator are
connected to a low, a high, and a low level,
respectively.
