SN74AVC4T245PWTG4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74AVC4T245PWTG4?
  The maximum operating frequency of the SN74AVC4T245PWTG4 is 320 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure signal integrity when using the SN74AVC4T245PWTG4?
  To ensure signal integrity, it's essential to follow proper PCB design and layout practices, such as using controlled impedance traces, minimizing signal routing, and providing adequate power and ground planes. Additionally, consider using termination resistors and/or series resistors to reduce signal reflections and ringing.
• Can I use the SN74AVC4T245PWTG4 in a 3.3V system?
  Yes, the SN74AVC4T245PWTG4 is a voltage translator that can operate from 1.2V to 3.6V, making it suitable for use in 3.3V systems. However, ensure that the input and output voltage levels are within the specified range for the specific application.
• How do I handle power sequencing when using the SN74AVC4T245PWTG4?
  To avoid latch-up or other issues, it's recommended to sequence the power supplies to the SN74AVC4T245PWTG4 such that the VCCA and VCCB supplies are powered up simultaneously, and the input signals are applied after the power supplies have reached their nominal values.
• What is the maximum current that the SN74AVC4T245PWTG4 can sink or source?
  The SN74AVC4T245PWTG4 can sink or source up to 24 mA of current per output pin, but the total current should not exceed the maximum package current rating of 100 mA.
