CD74FCT245E Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the CD74FCT245E?
  The maximum operating frequency of the CD74FCT245E is 100 MHz, but it can vary depending on the system design and capacitive loading.
• How do I ensure signal integrity when using the CD74FCT245E?
  To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors if necessary. Also, ensure that the power supply is clean and well-regulated.
• Can I use the CD74FCT245E in a 3.3V system?
  Yes, the CD74FCT245E is compatible with 3.3V systems, but the input voltage threshold may be affected. Ensure that the input signals meet the recommended voltage levels for proper operation.
• How do I handle bus contention when using multiple CD74FCT245E devices?
  To handle bus contention, use a bus arbiter or a multiplexer to ensure that only one device drives the bus at a time. Alternatively, use a bus buffer with a high-impedance state to prevent bus contention.
• What is the recommended power-up sequence for the CD74FCT245E?
  The recommended power-up sequence is to power up the VCC supply before applying any input signals. This ensures that the device is properly initialized and prevents any potential latch-up conditions.
