CD74ACT257E Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the CD74ACT257E is 4.5V to 5.5V, although it can operate as low as 3.5V with reduced performance.
  • To ensure signal integrity, use a low-impedance output driver, keep the output traces short, and use a termination resistor at the receiving end to minimize reflections and ringing.
  • The maximum frequency of operation for the CD74ACT257E is typically around 100 MHz, although this can vary depending on the specific application and operating conditions.
  • To avoid latch-up or other issues, ensure that the VCC pin is powered up before the input signals, and that the input signals are stable before the VCC pin is powered down.
  • Use a star topology for the power and ground connections, keep the input and output traces separate, and use a ground plane to minimize inductive loops and radiation.
