74ACT16543DGGR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the 74ACT16543DGGR?
  The recommended operating voltage range for the 74ACT16543DGGR is 4.5V to 5.5V, with a typical voltage of 5V.
• How do I handle the input pins when they are not in use?
  When input pins are not in use, they should be tied to VCC or GND through a pull-up or pull-down resistor to prevent floating inputs and ensure proper device operation.
• What is the maximum clock frequency supported by the 74ACT16543DGGR?
  The maximum clock frequency supported by the 74ACT16543DGGR is 100 MHz.
• Can I use the 74ACT16543DGGR in a 3.3V system?
  While the 74ACT16543DGGR is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage levels may not meet the required specifications, and the device may not function correctly at lower voltages.
• How do I ensure proper signal integrity when using the 74ACT16543DGGR?
  To ensure proper signal integrity, use proper PCB design techniques, such as using short signal traces, minimizing impedance mismatches, and adding termination resistors as needed.
