IC Identity Comparator Chips
8-input Magnitude Comparator Circuit
Identity Comparator. This Identity Comparator can be used perform comparisons of two 8-bit binary or BCD words. The output provides a P equals Q function. However unlike a Magnitude Comparator it does not provide a P greater than Q function. Note that most Magnitude Comparators supply the Identity Comparator function.
An Identity Comparator would be considered standard logic or glue logic when a discrete IC is used. However, because of the internal complexity, an Identity Comparator would also be considered an MSI Function [Medium Scale Integration].
Magnitude Comparator by Function:
Note in most cases when a 74xx device is listed, a 54xx device is also available.
74xx represents the commercial temperature range and 54xx represents the industrial temperature range [IC Prefixes].
