74HC273PW,118 datasheet by NXP Semiconductors

74HC273PW,118 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the 74HC273PW,118 can handle?
  The maximum clock frequency of the 74HC273PW,118 is 100 MHz, but it can vary depending on the operating voltage and temperature.
• How do I ensure that the flip-flops are properly initialized during power-up?
  To ensure proper initialization, connect the CLR (clear) input to a logic low level during power-up, and then release it after the power supply has stabilized.
• Can I use the 74HC273PW,118 as a level shifter?
  Yes, the 74HC273PW,118 can be used as a level shifter, but it's not recommended as it's not designed for that purpose. Instead, use a dedicated level shifter IC for reliable operation.
• What is the maximum current that the 74HC273PW,118 can sink or source?
  The maximum current that the 74HC273PW,118 can sink or source is 25 mA per output pin, but it's recommended to limit the current to 10 mA or less to ensure reliable operation.
• How do I handle the asynchronous clear input (CLR) during normal operation?
  During normal operation, the CLR input should be tied to a logic high level to prevent accidental clearing of the flip-flops. If you need to clear the flip-flops, use a pulse generator or a logic circuit to generate a brief logic low pulse on the CLR input.
