SN74AHCT574DBR datasheet by Texas Instruments

SN74AHCT574DBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74AHCT574DBR?
  The maximum operating frequency of the SN74AHCT574DBR is 100 MHz, but it can vary depending on the system design and capacitive load.
• How do I ensure signal integrity when using the SN74AHCT574DBR in a high-speed design?
  To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors or series resistors to reduce reflections and ringing.
• Can I use the SN74AHCT574DBR in a 3.3V system?
  Yes, the SN74AHCT574DBR is compatible with 3.3V systems, but ensure that the input voltage does not exceed the maximum rating of 5.5V.
• How do I handle power sequencing when using the SN74AHCT574DBR in a system with multiple power rails?
  Ensure that the VCC pin is powered up before the input signals, and that the input signals are stable before the clock signal is applied.
• What is the recommended pull-up resistor value for the OE (output enable) pin?
  The recommended pull-up resistor value for the OE pin is 1 kΩ to 10 kΩ, depending on the system requirements and noise immunity.
