CD74HCT540E datasheet by Texas Instruments

CD74HCT540E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for CD74HCT540E?
  The maximum frequency of operation for CD74HCT540E is 30 MHz.
• Can I use CD74HCT540E in a 5V system?
  Yes, CD74HCT540E is compatible with 5V systems, but it's 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 is active-low, meaning it should be connected to GND to enable the outputs. When OE is high, the outputs are in a high-impedance state.
• What is the propagation delay of CD74HCT540E?
  The propagation delay of CD74HCT540E is typically around 10-15 ns, but it can vary depending on the operating conditions and load capacitance.
• Can I use CD74HCT540E in a 3.3V system?
  While CD74HCT540E is primarily designed for 5V systems, it can be used in 3.3V systems with some limitations. However, the output voltage levels may not be compatible with 3.3V logic, and the device may not meet the specified timing parameters.
