LS404CN Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the LS404CN?
  The recommended operating temperature range for the LS404CN is -40°C to 125°C, although it can tolerate storage temperatures from -55°C to 150°C.
• How do I ensure the LS404CN is properly powered?
  The LS404CN requires a single 5V power supply, and it's recommended to use a decoupling capacitor (e.g., 100nF) close to the VCC pin to filter out noise and ensure stable operation.
• What is the maximum frequency of operation for the LS404CN?
  The LS404CN can operate up to 100 MHz, but the actual frequency limit depends on the specific application, PCB layout, and signal integrity considerations.
• How do I handle the LS404CN's output current limitations?
  The LS404CN has a limited output current of 20mA per pin. To avoid overloading, ensure that the output current is within the specified limit, and consider using external buffers or amplifiers if higher currents are required.
• What is the purpose of the NC (No Connect) pins on the LS404CN?
  The NC pins on the LS404CN are not connected internally and should be left unconnected or tied to a fixed voltage (e.g., GND or VCC) to prevent noise and interference.
