MC3021 is a Craftbook IC that performs a logical exclusive NOR (XNOR) operation on two inputs, outputting high when the inputs have the same state.

Details

• Second Line
  • [MC3021]

The IC compares the states of its two inputs and sets its output accordingly.

• The output is high if both inputs are high or both are low.
• The output is low if the inputs have different states.

Input 1	Input 2	Output
Low	Low	High
Low	High	Low
High	Low	Low
High	High	High

Examples

XNOR operation

line1:
line2: [MC3021]
line3:
line4:

With two input wires connected, the output is high when both inputs have the same state. If the inputs have different states, the output is low.
