74HC273D Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the 74HC273D can handle?
  The 74HC273D can handle clock frequencies up to 100 MHz, but this may 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 2.0-6.0V power supply, and decouple the power supply lines with 0.1uF and 10uF capacitors. Additionally, use a 10kΩ pull-up resistor on the OE (Output Enable) pin if it's not connected to a logic signal.
• 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 this should be limited to 100mA total current per package to avoid overheating.
• How do I handle the asynchronous clear (CLR) input?
  The CLR input is an asynchronous active-low input that clears the flip-flops when it's low. To ensure proper operation, CLR should be driven by a logic signal or connected to VCC through a pull-up resistor if not used.
• What is the propagation delay of the 74HC273D?
  The propagation delay of the 74HC273D is typically around 10-15ns, but this may vary depending on the specific application, operating conditions, and output load.
