SN74F521N Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74F521N is 100 MHz.
  • Yes, the SN74F521N is compatible with 3.3V systems, but it is recommended to use a voltage regulator to ensure a stable 5V supply.
  • The output enable (OE) pin should be tied low to enable the outputs. If OE is high, the outputs are in a high-impedance state.
  • The propagation delay of the SN74F521N is approximately 10 ns.
  • The SN74F521N is rated for operation up to 85°C, but it is recommended to derate the device for high-temperature applications.
