SN74ACT14DBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ACT14DBR?
  The maximum operating frequency of the SN74ACT14DBR is typically 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure signal integrity when using the SN74ACT14DBR in a high-speed application?
  To ensure signal integrity, use proper PCB layout techniques, such as using controlled impedance traces, minimizing trace lengths, and using termination resistors as needed. Additionally, consider using a signal integrity analysis tool to simulate and optimize your design.
• Can I use the SN74ACT14DBR in a 3.3V system?
  Yes, the SN74ACT14DBR is compatible with 3.3V systems. However, ensure that the input voltage (VCC) is within the recommended operating range of 4.5V to 5.5V, and that the output voltage is within the recommended range of 3.3V ± 0.3V.
• How do I handle power sequencing when using the SN74ACT14DBR in a system with multiple power rails?
  To ensure proper power sequencing, ensure that the power rails are sequenced in the correct order, typically with the digital power rail (VCC) coming up first, followed by the analog power rail (if applicable). Use power sequencing controllers or discrete components to control the power-up sequence.
• What is the recommended termination scheme for the SN74ACT14DBR?
  The recommended termination scheme for the SN74ACT14DBR is a series terminator (Rs) of 33-50 ohms, depending on the specific application and trace impedance. Consult the datasheet and application notes for more information.
