CD74ACT244E Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the CD74ACT244E is typically 100 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure signal integrity, use proper PCB design techniques, such as using controlled impedance traces, minimizing trace lengths, and using termination resistors as needed. Additionally, ensure that the power supply is clean and well-regulated.
  • Yes, the CD74ACT244E is compatible with 3.3V systems. However, ensure that the input signals are within the recommended voltage range (VCC - 0.5V to VCC + 0.5V) to maintain proper operation.
  • To ensure proper operation, power up the CD74ACT244E after the power supply has stabilized. If power sequencing is required, ensure that the VCC pin is powered up before the input signals.
  • The recommended termination scheme for the CD74ACT244E is to use a series terminator (e.g., 22-33 ohms) at the receiving end of the transmission line. This helps to reduce signal reflections and improve signal integrity.
