SN74HCT14PWRE4

The SN74HCT14PWRE4 is a hex inverting Schmitt-trigger buffer from Texas Instruments, designed for use in digital circuits. This component is part of the 74HCT family, which is known for its high-speed performance and compatibility with TTL (Transistor-Transistor Logic) levels, making it suitable for interfacing with various digital systems.

Key Features:

1. Hex Inverter Configuration: The SN74HCT14 contains six independent inverting buffers, each with Schmitt-trigger inputs. This means that it can take a single input signal and produce an inverted output, with the added benefit of noise immunity and hysteresis provided by the Schmitt-trigger design.

2. Schmitt-Trigger Inputs: The Schmitt-trigger inputs allow for clean transitions between high and low states, which is particularly useful in applications where the input signal may be slow or noisy. This feature helps to eliminate false triggering and ensures reliable operation.

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

4. High-Speed Operation: The SN74HCT14 is designed for high-speed applications, with propagation delays typically around 6 ns at a supply voltage of 5V. This makes it suitable for high-frequency digital circuits.

5. Low Power Consumption: The device features low power consumption, which is advantageous for battery-operated devices and applications where power efficiency is critical.

6. Pin Configuration: The SN74HCT14 is available in a 14-pin TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained applications. The pins are arranged in a standard configuration, allowing for easy integration into circuit designs.

7. Temperature Range: The operating temperature range for the SN74HCT14 is typically from -40°C to +125°C, making it suitable for a variety of environments, including industrial applications.

8. Logic Levels: The device is designed to recognize standard logic levels, with a high-level input voltage (VIH) typically around 2V and a low-level input voltage (VIL) around 0.8V, ensuring compatibility with other TTL and CMOS logic families.

Applications:

The SN74HCT14 is widely used in various applications, including:

• Signal conditioning and buffering
• Level shifting between different logic families
• Debouncing switches and buttons
• Generating clean clock signals
