The MM74C85 is a four-bit magnitude comparator which will perform comparison of straight binary or BCD codes
The MM74C85 is a four-bit magnitude comparator designed to compare straight binary or BCD codes. It features eight comparing inputs, three cascading inputs, and three outputs to determine if two four-bit words are greater than, less than, or equal to each other. The device supports expansion to 'N' stages for multi-bit comparisons.
| Supply Voltage Range | 3.0V to 15V |
|---|---|
| Propagation Delay (Vcc=5V) | 260 ns |
The MM74C85 performs comparison of straight binary or BCD codes.
Units can be cascaded by connecting the outputs of the least significant stage to the cascade inputs of the next-significant stage.
The device has a guaranteed noise margin of 1.0V.
