SN74F521N datasheet by Texas Instruments

SN74F521N Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74F521N?
  The maximum frequency of operation for the SN74F521N is 100 MHz.
• Can I use the SN74F521N in a 3.3V system?
  Yes, the SN74F521N is compatible with 3.3V systems, but it is recommended to use a voltage regulator to ensure a stable 5V supply.
• How do I handle the output enable (OE) pin?
  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.
• What is the propagation delay of the SN74F521N?
  The propagation delay of the SN74F521N is approximately 10 ns.
• Can I use the SN74F521N in a high-temperature environment?
  The SN74F521N is rated for operation up to 85°C, but it is recommended to derate the device for high-temperature applications.
