SN54AS245J datasheet by Texas Instruments

SN54AS245J Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN54AS245J?
  The maximum operating frequency of the SN54AS245J is 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure signal integrity when using the SN54AS245J?
  To ensure signal integrity, use proper PCB layout techniques, such as keeping signal traces short and away from noise sources, using impedance-matched transmission lines, and adding termination resistors as needed.
• Can I use the SN54AS245J in a 3.3V system?
  Yes, the SN54AS245J is compatible with 3.3V systems, but you may need to adjust the input and output voltage levels accordingly. Refer to the datasheet for specific voltage requirements.
• How do I handle power sequencing when using the SN54AS245J?
  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.
• What is the recommended termination scheme for the SN54AS245J?
  The recommended termination scheme for the SN54AS245J is to use a series terminator (e.g., 33 ohms) at the receiving end of the transmission line, and to match the impedance of the transmission line to the output impedance of the driver.
