SN7446AN Frequently Asked Questions (FAQs)

  • The SN7446AN can operate from -40°C to 85°C, but it's recommended to operate within 0°C to 70°C for optimal performance.
  • The SN7446AN requires a VCC supply voltage between 4.5V and 5.5V, and a GND pin connected to the system ground. Ensure that the input signals are within the recommended voltage range and that the output loads are within the specified current limits.
  • The SN7446AN can sink up to 16mA and source up to 2mA per output pin, but it's recommended to limit the current to 10mA per pin for reliable operation.
  • The SN7446AN has a thermal resistance of 60°C/W, so it's essential to provide adequate heat sinking, especially in high-temperature or high-current applications. Use a heat sink or a thermal pad to dissipate heat effectively.
  • The SN7446AN is designed for low-frequency applications up to 10MHz. While it may work at higher frequencies, its performance and reliability may degrade. For high-frequency applications, consider using a more suitable device.
