The SNJ54LS85J is an integrated circuit (IC) component that belongs to the 54LS series family. It is a 4-bit magnitude comparator, primarily used in digital electronics applications for comparing two binary numbers and determining their relationship (greater than, equal to, or less than).
This IC offers several key features that make it an essential component in various circuit designs. Some of these features include:
1. 4-bit comparison: The SNJ54LS85J allows for the comparison of two 4-bit binary numbers. It consists of four individual magnitude comparators, each capable of handling one bit of the input.
2. Parallel inputs: The IC accepts parallel inputs for both A and B bit values, allowing for efficient and simultaneous comparison.
3. Cascadable: The SNJ54LS85J can be cascaded to compare larger binary numbers by connecting the CARRY-OUT (Cn-1) of one comparator to the CARRY-IN (Cn) of the next comparator. This feature enables the comparison of multiple bytes or words.
4. Reference outputs: It provides four outputs: EQ (equal), GT (greater than), LT (less than), and CARRY-OUT. These outputs represent the relative relationship between the two input numbers and are useful for further processing or decision-making.
5. Active-low outputs: The EQ, GT, and LT outputs are active-low, meaning they are inverted versions of the actual output
