SN74LS390D Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS390D is 25 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure proper power and decoupling, use a 5V power supply, add a 0.1uF ceramic capacitor between VCC and GND, and use a 10uF electrolytic capacitor between VCC and GND for bulk decoupling.
  • The SN74LS390D can sink or source up to 16mA of current per output pin, but it's recommended to limit the current to 10mA or less to ensure reliable operation.
  • The asynchronous reset input (R) should be tied to VCC through a 1kΩ resistor and a 0.01uF capacitor to ensure proper reset operation.
  • No, the SN74LS390D is designed to operate at 5V and is not compatible with 3.3V systems. Using it in a 3.3V system may result in unreliable operation or damage to the device.
