SN74HC04NSR

The SN74HC04NSR is a hex inverter integrated circuit (IC) manufactured by Texas Instruments. It belongs to the 74HC (High-speed CMOS) family, which is known for its high-speed performance and low power consumption. Here’s a detailed description of the SN74HC04NSR:

General Features:

• Type: Hex Inverter
• Package: The "NSR" suffix indicates that this IC comes in a small outline integrated circuit (SOIC) package, specifically a 14-pin SOIC (Surface Mount) configuration.
• Technology: CMOS (Complementary Metal-Oxide-Semiconductor), which allows for low power operation and high noise immunity.
• Supply Voltage: The device operates over a wide supply voltage range, typically from 2V to 6V, making it versatile for various applications.
• Input/Output Logic Levels: The IC is compatible with standard TTL (Transistor-Transistor Logic) levels, ensuring it can interface with other logic families.

Functional Characteristics:

• Inversion: The SN74HC04 contains six independent inverter gates. Each gate takes a single input and produces an output that is the logical inverse of the input. For example, if the input is high (logic 1), the output will be low (logic 0), and vice versa.
• Propagation Delay: The typical propagation delay time for the inverter is around 10 ns at a supply voltage of 5V, which indicates how quickly the output responds to changes in the input.
• Fan-Out: The device can drive multiple inputs of other logic gates, with a typical fan-out of 10, meaning it can drive up to 10 standard TTL inputs.

Electrical Characteristics:

• Input Current: The input current is very low, typically in the microamp range, which contributes to the overall low power consumption of the device.
• Output Drive Capability: The outputs can source or sink a significant amount of current (up to 6 mA), allowing it to drive LEDs or other loads directly.
• Temperature Range: The operating temperature range is typically from -40°C to +125°C, making it suitable for industrial and automotive applications.
