SN74LV125ATDBR datasheet by Texas Instruments

SN74LV125ATDBR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74LV125ATDBR?
  The recommended operating voltage range for the SN74LV125ATDBR is 2.0 V to 3.6 V.
• How do I ensure signal integrity when using the SN74LV125ATDBR in a high-speed application?
  To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors as needed. Also, consider using a signal integrity analysis tool to simulate and optimize your design.
• Can I use the SN74LV125ATDBR in a 5V system?
  While the SN74LV125ATDBR is rated for 2.0 V to 3.6 V operation, it can tolerate 5V inputs, but the output voltage will be limited to the supply voltage (VCC). However, it's not recommended to operate the device at 5V for extended periods, as it may affect reliability and lifespan.
• How do I handle power sequencing when using the SN74LV125ATDBR in a system with multiple power rails?
  To avoid latch-up or other issues, ensure that the power rails are sequenced such that the VCC pin is powered up before the input signals, and powered down after the input signals. A power sequencing controller or a simple RC circuit can be used to achieve this.
• What is the maximum clock frequency supported by the SN74LV125ATDBR?
  The maximum clock frequency supported by the SN74LV125ATDBR is 100 MHz, but this can vary depending on the specific application, PCB design, and operating conditions. It's recommended to consult the datasheet and perform simulations or testing to determine the maximum clock frequency for your specific use case.
