The SN74LS85DR is a popular integrated circuit (IC) component that belongs to the 74LS series of logic devices, which are commonly used in digital circuit design. This particular IC is a 4-bit magnitude comparator, which means it is primarily used for comparing the relative magnitudes of two binary numbers.
Here are some key features and functionalities of the SN74LS85DR:
1. 4-bit Input/Output: The SN74LS85DR has four binary inputs, labeled A3, A2, A1, and A0, which are used to input the two 4-bit numbers to be compared. It also has three output pins, labeled A>B, A
