The DM74LS85N is an IC (Integrated Circuit) component that serves as a 4-bit magnitude comparator. It is a vital tool in digital electronics for comparing two 4-bit binary numbers and determining their relative magnitudes. Here's an overview of the key features of the DM74LS85N:
1. Magnitude Comparison: The DM74LS85N enables the comparison of two 4-bit binary numbers (A and B) to establish if they are equal or which one is greater in value.
2. 4-Bit Inputs: This component accepts two sets of 4-bit binary numbers as input, denoted as A and B. Each input can represent decimal numbers from 0 to 15.
3. Comparator Outputs: The DM74LS85N provides three output pins: EQ (Equals), GT (Greater Than), and LT (Less Than). These pins indicate the result of the comparison operation performed by the IC.
4. Cascading Capability: Multiple DM74LS85N chips can be cascaded together to compare more than two 4-bit binary numbers. By connecting the cascaded outputs to the subsequent IC's inputs, the magnitude comparison can be extended.
5. Binary Inputs: The A and B inputs accept binary signals (0 or 1) representing each bit of the 4-bit numbers. In total, eight input pins are used, with four pins dedicated to each 4-bit number
