SN74AVC8T245PWRE4 datasheet by Texas Instruments

SN74AVC8T245PWRE4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74AVC8T245PWRE4?
  The maximum operating frequency of the SN74AVC8T245PWRE4 is 320 MHz, but it can vary depending on the output load and supply voltage.
• How do I ensure signal integrity when using the SN74AVC8T245PWRE4?
  To ensure signal integrity, use a low-impedance output driver, keep the output traces short and well-terminated, and use a common ground plane to reduce noise and crosstalk.
• Can I use the SN74AVC8T245PWRE4 in a 3.3V system?
  Yes, the SN74AVC8T245PWRE4 is compatible with 3.3V systems, but ensure that the input voltage (VCC) is within the recommended range of 2.3V to 3.6V.
• How do I handle power sequencing when using the SN74AVC8T245PWRE4?
  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 applied.
• What is the recommended termination scheme for the SN74AVC8T245PWRE4?
  The recommended termination scheme is to use a series resistor (Rs) of 22-33 ohms and a parallel capacitor (Cp) of 1-2 pF at the output of each channel to reduce reflections and improve signal quality.
