SN7438N Frequently Asked Questions (FAQs)

  • The SN7438N can handle clock frequencies up to 10 MHz, but it's recommended to operate it at a maximum frequency of 5 MHz for reliable operation.
  • The SN7438N requires a single 5V power supply, and it's essential to decouple the power pins with a 0.1uF capacitor to ensure stable operation.
  • The SN7438N can sink or source up to 16mA of current per output pin, but it's recommended to limit the current to 10mA per pin for reliable operation.
  • The propagation delay of the SN7438N is typically around 10-15ns, and it's essential to consider this delay when designing your circuit to ensure proper timing and synchronization.
  • The SN7438N has a relatively high noise immunity, but it's still essential to take precautions to minimize noise and ensure reliable operation, such as using decoupling capacitors and shielding the circuit.
