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

NOTgate

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

ANDgate

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

ORgate

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

NANDgate

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

XORgate

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
