Disadvantages

• Limited number of inputs: The MC74LCX86DTR2 supports only two inputs per gate, which may restrict certain complex logic operations.
• Narrow operating temperature range: The IC is specified for use within -40°C to +85°C, limiting its suitability for extreme temperature environments.

Working Principles

The MC74LCX86DTR2 operates based on the principles of XOR (exclusive OR) logic. It takes two input signals and produces an output signal that is high (logic 1) only when the inputs differ. When both inputs are the same, the output is low (logic 0). This functionality allows the IC to perform various logical operations in digital circuits.
