• Outputs high (1) if the number of high inputs is odd, otherwise outputs low (0).
• Provides four independent XOR gates in a single package.
• High-speed operation with low power consumption.
• Compatible with TTL (Transistor-Transistor Logic) input/output levels.

Advantages and Disadvantages

Advantages: - Compact design with multiple XOR gates in a single package. - Wide supply voltage range allows flexibility in various applications. - Low propagation delay enables high-speed signal processing. - High output current capability for driving external loads.

Disadvantages: - Limited number of inputs per gate (only 2). - Not suitable for applications requiring more complex logic operations. - Relatively higher power dissipation compared to some newer logic families.

Working Principles

The MC74ACT86NG is based on the XOR gate logic, which follows the truth table:

A | B | Y ---|---|--- 0 | 0 | 0 0 | 1 | 1 1 | 0 | 1 1 | 1 | 0

It performs an exclusive OR operation on the two input signals (A and B) and produces the corresponding output (Y). The gate operates by comparing the logical states of the inputs and generating the appropriate output based on the XOR function.
