SN74LS674DW Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS674DW is 20 MHz.
  • The SN74LS674DW requires a single 5V power supply, and it's recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper operation.
  • The SN74LS674DW can sink or source up to 24mA of current per output pin.
  • The RST input should be tied to VCC through a pull-up resistor (e.g., 1kΩ) and connected to a reset signal or a push-button switch to ensure proper reset operation.
  • No, the SN74LS674DW is designed to operate at 5V, and using it in a 3.3V system may not guarantee proper operation or may even damage the device.
