SN74ABTR2245DW datasheet by Texas Instruments

SN74ABTR2245DW Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74ABTR2245DW?
  The recommended operating voltage range for the SN74ABTR2245DW is 3.3V to 5V, with a typical operating voltage of 3.3V.
• How do I ensure signal integrity when using the SN74ABTR2245DW in a high-speed application?
  To ensure signal integrity, use a low-impedance PCB design, keep signal traces short and away from noise sources, and use termination resistors as needed. Additionally, consider using a signal integrity analysis tool to simulate and optimize your design.
• Can I use the SN74ABTR2245DW in a 5V system with 3.3V logic?
  Yes, the SN74ABTR2245DW is 5V-tolerant, meaning it can accept 5V input signals while operating at a 3.3V supply voltage. However, ensure that the output voltage is within the 3.3V logic level to avoid damage to downstream devices.
• What is the maximum data rate supported by the SN74ABTR2245DW?
  The SN74ABTR2245DW supports data rates up to 100 Mbps, making it suitable for high-speed applications such as USB, Ethernet, and PCIe.
• How do I handle power sequencing when using the SN74ABTR2245DW in a power-up/down sequence?
  To avoid damage or incorrect operation, ensure that the power supply voltage (VCC) is applied before the input signals, and that the input signals are stable before the output enable (OE) is asserted. A power sequencing circuit or a voltage supervisor can help ensure proper power-up/down sequencing.
