In the process of testing a 74LS283 4-bit parallel adder, the following logic levels were observed on its pins: (Please check the datasheet of 74LS283 for more details.) Pin number 1 Logic level HIGH 2 HIGH 3 HIGH 4 HIGH 5 LOW 6 LOW 7 LOW 8 LOW 9 HIGH 10 LOW 11 HIGH 12 LOW 13 HIGH 14 HIGH 15 HIGH HIGH 16 Determine if the IC is functioning properly. If not, what should be the correct logic level at each pin. You need to give as much analysis details as possible.

Čreate a mechanism to detect when the output is decimal value '11' using 2 input logic gates.
