74VHC573TTR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the 74VHC573TTR?
  The maximum operating frequency of the 74VHC573TTR is 100 MHz, but it can vary depending on the output load and supply voltage.
• How do I ensure that the output signals are not distorted or skewed?
  To ensure that the output signals are not distorted or skewed, it is recommended to use a low-impedance output driver, keep the output traces short, and use a good quality PCB with minimal noise and crosstalk.
• Can I use the 74VHC573TTR as a level translator?
  Yes, the 74VHC573TTR can be used as a level translator, but it is not recommended as it is not designed for level translation. Instead, use a dedicated level translator IC for this purpose.
• What is the maximum current that the 74VHC573TTR can sink or source?
  The maximum current that the 74VHC573TTR can sink or source is 25 mA per output pin, but it is recommended to keep the output current below 10 mA to ensure reliable operation.
• How do I handle the power-up and power-down sequencing of the 74VHC573TTR?
  It is recommended to power up the 74VHC573TTR after the power supply has stabilized, and to power it down before the power supply is turned off. This ensures that the device operates within its specified voltage range and prevents latch-up or other issues.
