General description
The HEF4585B is a 4-bit magnitude comparator that compares two 4-bit words, A and B,
and determines whether A is greater than B, A is equal to B, or A is less than B. Each
word has four parallel inputs (A0 to A3 and B0 to B3) with A3 and B3 being the most
significant inputs. Three outputs are provided: A greater than B (QA>B), A less than B
(QA<B) and A equal to B (QA=B). Three expander inputs (IA>B, IA<B, and IA=B) allow
cascading of the devices, to compare 8, 12, 16, ..., bits without external gates.
To operate a single device or a device in the least significant position in a cascaded chain,
the expander inputs are connected as follows: IA=B = IA>B = HIGH and IA<B = LOW. All
other cascaded devices have IA=B and IA<B connected to QA=B and QA<B respectively
of the previous (less significant) device in the chain, while input IA>B is connected to a
HIGH (see
Figure 6
). Operation is not restricted to pure binary code; the devices will work
with any monotonic code.
Table 3
describes the operation of the device under all possible
logic conditions.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
