74C85 - 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

  • s Wide supply voltage range: 3.0V to 15V s Guaranteed noise margin: 1.0V s High noise immunity: 0.4 VCC (typ. ) s Low power: TTL compatibility: fan out of 2 driving 74L s Expandable to 'N' stages s Applicable to binary or BCD s Low power pinout: 74L85 Ordering Code: Order Number Package Number Package.

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.
