74HC14DB,118 datasheet by NXP Semiconductors

74HC14DB,118 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the 74HC14DB,118?
  The maximum operating frequency of the 74HC14DB,118 is 100 MHz.
• Can I use the 74HC14DB,118 in a 5V system?
  Yes, the 74HC14DB,118 is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
• How do I handle the Schmitt trigger inputs to prevent oscillation?
  To prevent oscillation, ensure that the input signals have a clean, fast transition (typically <10ns) and avoid slow-rising or noisy signals. You can also add a small capacitor (e.g., 10nF) between the input and GND to filter out high-frequency noise.
• What is the recommended power-on reset (POR) circuit for the 74HC14DB,118?
  A simple POR circuit can be implemented using a resistor, capacitor, and diode. For example, connect a 10kΩ resistor between VCC and a 10μF capacitor, and a diode (e.g., 1N4148) between the capacitor and GND. This ensures a clean power-on reset.
• Can I use the 74HC14DB,118 as a simple inverter or buffer?
  Yes, the 74HC14DB,118 can be used as a simple inverter or buffer by connecting the input to the output through a resistor (e.g., 1kΩ). This configuration can provide a simple logic inversion or signal buffering.
