SN7403N datasheet by Texas Instruments

SN7403N Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN7403N?
  The maximum frequency of operation for the SN7403N is typically around 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the SN7403N is properly decoupled from the power supply?
  To ensure proper decoupling, use a 0.1 μF ceramic capacitor between the VCC pin and GND pin, and place it as close to the device as possible. Additionally, use a 10 μF electrolytic capacitor between the power supply and GND to filter out any noise.
• What is the maximum current that the SN7403N can sink or source?
  The SN7403N can sink or source up to 16 mA of current per output, but it's recommended to limit the current to 10 mA or less to ensure reliable operation.
• How do I handle the heat generated by the SN7403N?
  The SN7403N is designed to operate within a temperature range of 0°C to 70°C. To handle heat generation, ensure good airflow around the device, and consider using a heat sink if the device is expected to operate at high temperatures or high frequencies.
• Can I use the SN7403N in a 3.3V or 5V system?
  Yes, the SN7403N is compatible with both 3.3V and 5V systems. However, ensure that the input voltage levels are compatible with the device's input voltage thresholds, and that the output voltage levels are compatible with the load devices.
