Additional Details

The TC4077BF typically comes in a 14-pin package. The output of an XNOR gate is high when both inputs are the same (either both high or both low) and low when the inputs are different. It is commonly used in applications where signal comparison or parity checking is required. Proper decoupling capacitors should be used near the power supply pins to ensure stable operation. Its symmetrical behavior makes it suitable for use in both combinational and sequential logic circuits.
