CD74HC245E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC245E?
  The CD74HC245E can operate at frequencies up to 50 MHz.
• How do I ensure signal integrity when using the CD74HC245E?
  To ensure signal integrity, use a low-impedance output driver, minimize trace lengths, and use a ground plane to reduce noise and electromagnetic interference (EMI).
• Can I use the CD74HC245E in a 5V system?
  Yes, the CD74HC245E is compatible with 5V systems, but ensure that the input voltage (VCC) is within the recommended operating range of 2V to 6V.
• How do I handle power-up and power-down sequencing with the CD74HC245E?
  To prevent latch-up and ensure proper operation, ensure that the input signals are stable and valid before applying power to the device, and follow a controlled power-down sequence to prevent data loss or corruption.
• What is the recommended termination scheme for the CD74HC245E?
  Use a series terminator (e.g., 33Ω to 50Ω) at the receiving end of the transmission line to minimize reflections and ensure signal integrity.
