Description

CD4063BMS is a 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 CD4063BMS has eight comparing inputs (A3, B3, through

A0, B0), three outputs (A B) and three cascading

inputs (A B) that permit systems designers to

expand the comparator function to 8, 12, 16 . . . 4N bits. When a

single CD4063BMS is used, the cascading inputs are connected

as follows: (A B) = low.

For words longer than 4 bits, CD4063BMS devices 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) on the

least significant comparator are connected to a low, a high, and a

low level, respectively.

The CD4063BMS is supplied in these 16 lead outline packages:
