SN74HC273DWRG4 Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the SN74HC273 is 20 MHz, but this can vary depending on the specific application and operating conditions.
  • Make sure to connect the VCC pin to a stable 5V power supply, and the GND pin to a solid ground. Also, ensure that the reset pin (MR) is properly tied to VCC or a reset signal to initialize the device.
  • The typical propagation delay time for the SN74HC273 is around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
  • No, the SN74HC273 is specified to operate at 5V, and using it with a 3.3V power supply may not guarantee proper operation or reliability.
  • The output enable (OE) pin should be tied to GND to enable the outputs, or to VCC to disable the outputs. Leaving the OE pin floating can cause unpredictable behavior.
