Functional Features

• Quad 2-input AND gate: The SN74ACT08DR consists of four independent AND gates, each with two inputs and one output.
• High-speed operation: It operates at high speeds due to its advanced CMOS technology.
• Wide supply voltage range: The IC can operate within a supply voltage range of 4.5V to 5.5V.
• Low power consumption: The maximum quiescent current is only 8µA, making it energy-efficient.

Advantages and Disadvantages

Advantages: - High-speed operation allows for quick signal processing. - Wide supply voltage range provides flexibility in various applications. - Low power consumption reduces energy usage.

Disadvantages: - Limited to AND gate functionality, limiting its use in more complex logic operations. - Requires external components for complete circuit implementation.

Working Principles

The SN74ACT08DR operates based on the principles of digital logic. It performs the logical AND operation on two input signals and produces an output signal based on the following truth table:

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

The output Y is high (logic level 1) only when both inputs A and B are high; otherwise, the output is low (logic level 0).
