The DM74LS85N from On Semiconductor is a versatile 4-bit magnitude comparator. This integrated circuit is capable of performing comparisons on straight binary or BCD codes, providing three distinct outputs: A>B, A<B, and A=B. These outputs are fully decoded and externally available, allowing for direct integration into digital logic systems.
Designed for flexibility, the DM74LS85N is fully expandable to any number of bits without the need for external gates. This is achieved by cascading multiple units, where the outputs of a less-significant bit stage are connected to the inputs of the next more-significant bit stage. This cascading path introduces only a minimal two-gate-level delay, ensuring efficient comparison times even for extended word lengths.
Key electrical characteristics include an operating voltage range of 4.75V to 5.25V and a typical power dissipation of 52 mW. The maximum propagation delay for 4-bit words is rated at 42 ns at 5V and 50pF. The device operates within a temperature range of 0°C to 70°C.
The DM74LS85N is supplied in a 16-lead PDIP package, suitable for through-hole mounting. Its robust design and expandability make it a suitable component for various digital comparison tasks in electronic designs.
