The SN74LS14NS is an integrated circuit (IC) component from the 74LS family series, manufactured by Texas Instruments. It is a hex Schmitt-trigger inverter, commonly used in digital electronic systems to clean up noisy digital signals and provide stable outputs.
Key features of the SN74LS14NS include:
1. Hex Schmitt-Trigger Inverter: The IC contains six independent Schmitt-trigger inverters in a single package. Each inverter can be used individually or together, providing flexibility in various applications.
2. Schmitt-Trigger Input: Schmitt triggers have hysteresis, meaning the input signal must pass a specific threshold voltage to change the output state. This feature helps in minimizing problems caused by slow or noisy input signals.
3. Wide Voltage Range: The operating voltage range for SN74LS14NS is typically between 4.75V and 5.25V, making it compatible with standard TTL logic and other 5V CMOS systems.
4. High-Speed Performance: The IC has a fast propagation delay of about 9 ns, enabling it to process signals quickly, which is essential in high-speed digital circuits.
5. Standard Logic Levels: The inputs and outputs of the SN74LS14NS are compatible with standard TTL logic levels. The logic-level low input threshold is typically around 0.8V, while the logic high threshold is approximately 2V
