MM74C85 - 4-Bit Magnitude Comparator

General Description

The MM74C85 is a four-bit magnitude comparator which will perform comparison of straight binary or BCD codes.

The circuit consists of eight comparing inputs (A0, A1, A2, A3, B0, B1, B2, B3), three cascading inputs (A > B, A < B and A = B), and three outputs (A > B, A < B and A = B).

Key Features

MM74C85 4-Bit Magnitude Comparator October 1987 Revised January 1999 MM74C85 4-Bit Magnitude Comparator General Description The MM74C85 is a four-bit magnitude comparator which will perform comparison of straight binary or BCD codes. The circuit consists of eight comparing inputs (A0, A1, A2, A3, B0, B1, B2, B3), three cascading inputs (A > B, A < B and A = B), and three outputs (A > B, A < B and A = B). This device compares two four-bit words (A and B) and determines whether they are “greater than,” “less than,” or “equal to” each other by a high level on the appropriate output.
