SN74HC273PWR datasheet by Texas Instruments

SN74HC273PWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HC273PWR can handle?
  The maximum clock frequency of the SN74HC273PWR is 35 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
• How do I ensure that the SN74HC273PWR is properly powered and decoupled?
  To ensure proper power and decoupling, connect the VCC pin to a 5V power supply, and decouple the power pins with 0.1uF and 10uF capacitors. Additionally, use a 10kΩ pull-up resistor on the clock input (CLK) to prevent clock signal degradation.
• What is the maximum current that the SN74HC273PWR can sink or source?
  The SN74HC273PWR can sink or source up to 25mA of current per output pin, but it's recommended to limit the current to 10mA or less to ensure reliable operation.
• How do I handle the asynchronous reset (R) input?
  The asynchronous reset (R) input should be tied to VCC through a 1kΩ resistor and a 0.1uF capacitor to ensure proper reset operation. A low signal on the R input resets the flip-flops.
• What is the propagation delay of the SN74HC273PWR?
  The propagation delay of the SN74HC273PWR is typically around 10ns, but it can vary depending on the operating conditions and the load capacitance.
