SN74AS867NT Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the SN74AS867NT is 4.5V to 5.5V, with a typical operating voltage of 5V.
  • The SN74AS867NT has a thermal pad on the bottom of the package, which should be connected to a thermal ground plane on the PCB to dissipate heat. Additionally, ensure good airflow around the device and use thermal vias to dissipate heat to the other side of the board if necessary.
  • The maximum clock frequency that the SN74AS867NT can handle is 100 MHz, but this can vary depending on the specific application and operating conditions.
  • To ensure signal integrity when using the SN74AS867NT, use controlled impedance traces, minimize trace lengths, and use termination resistors as necessary. Additionally, ensure that the power supply is clean and well-regulated, and use decoupling capacitors to reduce noise.
  • The SN74AS867NT is a 5V device, but it can be used with 3.3V logic with some limitations. The output voltage of the device will be 5V, but it can be used with 3.3V inputs. However, the device may not meet its specified timing and voltage parameters when operated at 3.3V.
