Logic gate

Logic gates are game elements introduced in Chip's Challenge 2. They perform a logical operation on one or two wire inputs and produce a single output. They consist of the inverter, AND gate, OR gate, NAND gate, and XOR gate. There also exist NOR and XNOR logic gates, but these are not present in Chip's Challenge 2.

Inverter

The inverter, also called the NOT gate, accepts a single input and inverts the signal. If its input signal is ON, the output signal will be OFF. If its input signal is OFF, the output signal will be ON.

INPUT	OUTPUT
A	NOT A
0	1
1	0

AND gate

The AND gate accepts two inputs. If both inputs signals are ON, the output signal will be ON. Otherwise, the output signal will be OFF.

INPUT		OUTPUT
A	B	A AND B
0	0	0
0	1	0
1	0	0
1	1	1

OR gate

The OR gate accepts two inputs. If at least one of the input signals are ON, the output signal will be ON. Otherwise, the output signal will be OFF.

INPUT		OUTPUT
A	B	A OR B
0	0	0
0	1	1
1	0	1
1	1	1

NAND gate

The NAND gate accepts two inputs. It is equivalent to an AND gate immediately followed by an inverter. If both input signals are ON, the output signal will be OFF. Otherwise, the output signal will be on.

INPUT		OUTPUT
A	B	A NAND B
0	0	1
0	1	1
1	0	1
1	1	0

XOR gate

The XOR gate gate accepts two inputs and performs an exclusive or operation. If one or the other of the two input signals is ON, the output signal will be ON. If neither input signals are ON or both input signals are ON, the output signal will be OFF.

INPUT		OUTPUT
A	B	A XOR B
0	0	0
0	1	1
1	0	1
1	1	0
