CD74ACT32E Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the CD74ACT32E?
  The maximum operating frequency of the CD74ACT32E is 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure signal integrity when using the CD74ACT32E in a high-speed application?
  To ensure signal integrity, use proper PCB layout techniques, such as using short signal traces, minimizing impedance mismatch, and using termination resistors if necessary. Additionally, consider using a signal integrity analysis tool to simulate and optimize your design.
• Can I use the CD74ACT32E in a 3.3V system, and if so, what are the power supply requirements?
  Yes, the CD74ACT32E can be used in a 3.3V system. The recommended power supply voltage range is 2.0V to 5.5V, with a typical operating voltage of 3.3V. Ensure that the power supply is stable and within the recommended range to ensure proper device operation.
• How do I handle power sequencing when using the CD74ACT32E in a system with multiple power domains?
  When using the CD74ACT32E in a system with multiple power domains, ensure that the power supply to the device is sequenced correctly to prevent damage or malfunction. Typically, the power supply to the CD74ACT32E should be turned on after the power supply to the input signals, and turned off before the power supply to the input signals.
• What is the recommended termination scheme for the CD74ACT32E?
  The recommended termination scheme for the CD74ACT32E depends on the specific application and signal frequency. For high-speed applications, a series termination resistor (Rs) of 22-33 ohms is recommended, while for low-speed applications, a parallel termination resistor (Rt) of 1k-10k ohms can be used.
