74HC273D,652 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the 74HC273D can handle?
  The maximum clock frequency of the 74HC273D is 40 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the 74HC273D is properly powered and decoupled?
  To ensure proper power and decoupling, connect the VCC pin to a stable 2-6V power supply, and decouple the power supply lines with 0.1uF and 10uF capacitors.
• What is the maximum current that the 74HC273D can sink or source?
  The 74HC273D can sink or source up to 25mA of current per output pin, but it's recommended to limit the current to 10mA per pin to ensure reliable operation.
• How do I handle the asynchronous reset input (nRST) of the 74HC273D?
  The nRST input should be connected to a pull-up resistor (e.g., 1kΩ) and a capacitor (e.g., 100nF) to ensure a clean reset signal. A low-level signal on nRST resets the flip-flops.
• What is the propagation delay of the 74HC273D?
  The propagation delay of the 74HC273D is typically around 10-15ns, but it can vary depending on the specific application and operating conditions.
