SN74HCT04DR

The SN74HCT04DR is a hex inverter integrated circuit (IC) manufactured by Texas Instruments. It belongs to the 74HCT family of logic devices, which are designed to operate with TTL (Transistor-Transistor Logic) levels while being compatible with CMOS (Complementary Metal-Oxide-Semiconductor) technology. This makes the SN74HCT04DR suitable for a wide range of digital applications.

Key Features:

1. Hex Inverter Configuration: The SN74HCT04 contains six independent inverter gates. Each gate takes a single input and produces an output that is the logical inverse of the input. This allows for versatile logic design in digital circuits.

2. Voltage Range: The device operates over a wide supply voltage range, typically from 4.5V to 5.5V, making it compatible with standard logic levels.

3. Input and Output Characteristics:

   • Input Voltage Levels: The input high voltage (VIH) is typically around 2.0V minimum, while the input low voltage (VIL) is a maximum of 0.8V. This ensures reliable operation with TTL logic levels.
   • Output Drive Capability: The outputs can drive standard TTL loads, providing a high output current capability, which is essential for driving other logic devices or loads in a circuit.

4. Propagation Delay: The typical propagation delay time for the SN74HCT04 is around 10-15 nanoseconds, depending on the load and supply voltage. This fast switching speed makes it suitable for high-speed applications.

5. Package Type: The "DR" suffix in the part number indicates that the device is available in a small-outline package (SOP), which is compact and suitable for surface-mount technology (SMT). This package type helps save space on printed circuit boards (PCBs).

6. Temperature Range: The SN74HCT04 is designed to operate over a standard temperature range of -40°C to +125°C, making it suitable for both commercial and industrial applications.

7. Power Consumption: The device is designed to have low power consumption, which is a critical factor in battery-operated and energy-efficient designs.

Applications:

The SN74HCT04DR is widely used in various applications, including:

• Digital signal processing
• Logic level conversion
• Signal inversion in communication systems
• General-purpose logic circuits
• Timing and control applications

Conclusion:

The SN74HCT04DR from Texas Instruments is a versatile and reliable hex inverter that combines the benefits of TTL and CMOS technologies. Its robust performance, compatibility with standard logic levels, and compact packaging make it an excellent choice for a wide range of digital applications in both consumer and industrial electronics.
