PART B: 4-bit binary adder 4. Naturally, life is much easier if we use an IC, when it comes to adding multi-bit binary numbers! Use a 74LS283 4-bit parallel adder shown on the right to add two 4-bit binary numbers. Write down the pin number of each pin on the schematic diagram. 5. Connect each bit of the two 4-bit binary numbers to a toggle switch. Note that in labeling the inputs, the most significant bit of each number ( \( A, B \), or \( \Sigma) \) has the subscript 4 , the least significant bit the subscript 1. Thus, you will be using 8 switches in total. \( C_{\text {in }} \) should be grounded. 6. Use 5 LEDs to observe \( C_{\text {out }} \) and \( \sum_{1} \) to \( \sum_{4} \). Perform \( (A+B) \) for each combination of \( A \) and \( B \) in the table below to complete the table Figure 2. 4-bit binary adder
