74ACT125TTR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the 74ACT125TTR?
  The recommended operating voltage range for the 74ACT125TTR is 4.5V to 5.5V, although it can operate down to 3.5V with reduced performance.
• How do I ensure signal integrity when using the 74ACT125TTR as a buffer?
  To ensure signal integrity, use a low-impedance output driver, keep the output traces short and well-terminated, and avoid overloading the output with too many inputs.
• Can I use the 74ACT125TTR as a level translator between 3.3V and 5V logic?
  Yes, the 74ACT125TTR can be used as a level translator between 3.3V and 5V logic, but ensure that the input voltage is within the recommended operating range and that the output is properly terminated.
• What is the maximum frequency of operation for the 74ACT125TTR?
  The maximum frequency of operation for the 74ACT125TTR is typically around 100MHz, but this can vary depending on the specific application and operating conditions.
• How do I handle power sequencing when using multiple 74ACT125TTR devices?
  When using multiple 74ACT125TTR devices, ensure that the power supplies are sequenced correctly to avoid latch-up or other issues. Typically, power up the devices in the order of VCC, then inputs, and finally outputs.
