SN74LVT245BDBRE4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74LVT245BDBRE4?
  The maximum operating frequency of the SN74LVT245BDBRE4 is 100 MHz, but it can vary depending on the output load and the system design.
• How do I ensure signal integrity when using the SN74LVT245BDBRE4?
  To ensure signal integrity, use a low-impedance output driver, keep the output traces short, and use a termination resistor at the receiving end. Also, consider using a signal integrity analysis tool to simulate the signal behavior.
• Can I use the SN74LVT245BDBRE4 in a 3.3V system?
  Yes, the SN74LVT245BDBRE4 is compatible with 3.3V systems. It has a wide operating voltage range of 2.3V to 3.6V, making it suitable for use in 3.3V systems.
• How do I handle power sequencing when using the SN74LVT245BDBRE4?
  To avoid latch-up or other issues, ensure that the VCC supply is powered up before the input signals. Also, ensure that the input signals are stable before powering up the VCC supply.
• What is the maximum current that the SN74LVT245BDBRE4 can sink or source?
  The SN74LVT245BDBRE4 can sink or source up to 24 mA of current per output pin, but it's recommended to limit the current to 12 mA per pin to ensure reliable operation.
