SN74ACT8990FNR Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the SN74ACT8990FNR is 4.5V to 5.5V, with a typical voltage of 5V.
  • To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors as needed. Also, follow the recommended layout guidelines in the datasheet.
  • While the SN74ACT8990FNR is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage will be reduced, and the device may not meet all the specified timing parameters.
  • To avoid latch-up or other issues, ensure that the power supply voltage (VCC) is applied before the input signals, and that the input signals are stable before the clock signal is applied.
  • The maximum clock frequency supported by the SN74ACT8990FNR is 100 MHz, but this can vary depending on the specific application and operating conditions.
