SN74HCT08N

The SN74HCT08N is a quad 2-input AND gate integrated circuit (IC) manufactured by Texas Instruments. It belongs to the HCT (High-speed CMOS TTL-compatible) family, which means it is designed to be compatible with TTL (Transistor-Transistor Logic) levels while providing the benefits of CMOS technology, such as low power consumption and high noise immunity.

Key Features:

1. Quad 2-Input AND Gates: The SN74HCT08N contains four independent 2-input AND gates. Each gate can take two binary inputs and produce a single binary output, where the output is high (logic '1') only when both inputs are high.

2. Logic Levels: The device operates with a supply voltage range of 4.5V to 5.5V, making it suitable for standard digital logic applications. The input voltage levels are compatible with TTL logic levels, allowing it to interface easily with other TTL devices.

3. Propagation Delay: The typical propagation delay time for the SN74HCT08N is around 10 ns at a supply voltage of 5V, which makes it suitable for high-speed applications.

4. Low Power Consumption: The HCT series is designed to consume less power compared to traditional TTL devices, making it ideal for battery-operated and energy-efficient applications.

5. Temperature Range: The operating temperature range for the SN74HCT08N is typically from -40°C to +125°C, allowing it to be used in a variety of environments, including industrial applications.

6. Pin Configuration: The SN74HCT08N is available in various package types, including DIP (Dual In-line Package) and SOIC (Small Outline Integrated Circuit). The DIP version typically has 14 pins, with each gate occupying two pins for inputs and one pin for the output.

7. Applications: This IC is commonly used in digital logic circuits, data processing, and control applications. It can be found in various devices, including computers, communication equipment, and consumer electronics.

8. Logic Functionality: The truth table for the AND gates in the SN74HCT08N is straightforward:

   • If both inputs are 0 (low), the output is 0 (low).
   • If one input is 0 and the other is 1 (high), the output is 0 (low).
   • If both inputs are 1 (high), the output is 1 (high).

Summary:

The SN74HCT08N is a versatile and reliable quad 2-input AND gate that combines the advantages of CMOS technology with TTL compatibility. Its low power consumption, high-speed operation, and wide temperature range make it an excellent choice for a variety of digital logic applications. Whether used in simple logic circuits or more complex digital systems, the SN74HCT08N provides robust performance and reliability.
