74HCT04D,653

The 74HCT04D,653 is a hex inverter IC (integrated circuit) manufactured by Nexperia, designed for use in digital logic applications. It belongs to the 74HCT family, which is a high-speed CMOS (Complementary Metal-Oxide-Semiconductor) logic family that is compatible with TTL (Transistor-Transistor Logic) levels. This makes it suitable for interfacing with other TTL devices while providing the benefits of lower power consumption and higher noise immunity.

Key Features:

1. Hex Inverter Functionality: The 74HCT04D contains six independent inverter gates. Each gate takes a single input and produces an output that is the logical negation of the input. This allows for versatile logic operations in digital circuits.

2. Supply Voltage: The device operates over a supply voltage range of 4.5V to 5.5V, making it compatible with standard TTL logic levels.

3. Input and Output Characteristics:

   • Input Voltage Levels: The input high voltage (VIH) is typically around 2.0V, while the input low voltage (VIL) is around 0.8V, ensuring compatibility with TTL logic.
   • Output Drive Capability: The outputs can drive standard TTL loads, providing a high output current capability, typically around 6 mA.

4. Propagation Delay: The typical propagation delay time for the inverter gates is around 10 ns, allowing for fast switching speeds suitable for high-speed applications.

5. Power Consumption: The 74HCT04D is designed to operate with low power consumption, making it ideal for battery-operated devices and energy-efficient designs.

6. Package Type: The "D" in the part number indicates that the device is available in a surface-mount package, specifically the SOIC (Small Outline Integrated Circuit) package. This compact form factor is suitable for modern PCB designs where space is a premium.

7. Temperature Range: The device typically operates within a temperature range of -40°C to +125°C, making it suitable for a wide variety of applications, including industrial and automotive environments.

Applications:

The 74HCT04D,653 is widely used in various applications, including:

• Logic level conversion between TTL and CMOS devices.
