74AVC4TD245BQ Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the 74AVC4TD245BQ?
  The maximum operating frequency of the 74AVC4TD245BQ is 320 MHz, but it can vary depending on the output load and supply voltage.
• How do I ensure signal integrity when using the 74AVC4TD245BQ?
  To ensure signal integrity, use a low-impedance output driver, keep the output traces short and well-terminated, and use a ground plane to reduce noise and crosstalk.
• Can I use the 74AVC4TD245BQ in a 3.3V system?
  Yes, the 74AVC4TD245BQ is compatible with 3.3V systems, but ensure that the input signals are within the recommended voltage range (VCC - 0.5V to VCC + 0.5V) to maintain proper operation.
• How do I handle power sequencing when using the 74AVC4TD245BQ?
  To avoid latch-up or damage, ensure that the power supply voltage (VCC) is applied before the input signals, and that the input signals are stable before the power supply voltage is removed.
• What is the recommended termination scheme for the 74AVC4TD245BQ?
  The recommended termination scheme is a series terminator (Rs) of 22-33 ohms, followed by a parallel terminator (Rt) of 50-75 ohms, to minimize reflections and ensure signal integrity.
