Description

A<B
CD4585BMS 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.

WORD “B”
The CD4585BMS has eight comparing inputs (A3, B3,
through A0, B0), three outputs (A < B, = B, A > B) and three
cascading inputs (A < B, A = B, A > B) that permit system
designers to expand the comparator function to 8, 12, 16 . .
.4N bits. When a single CD4585BMS is used, the cascading
inputs are connected as follows: (A < B) = low, (A = B) =
high, (A > B) = high.
