M74HC574M1R datasheet by STMicroelectronics

M74HC574M1R Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the M74HC574M1R?
  The maximum clock frequency for the M74HC574M1R is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the AC characteristics table in the datasheet for more information.
• How do I handle the power-up reset sequence for the M74HC574M1R?
  The M74HC574M1R has an asynchronous reset input (RST) that should be asserted low during power-up to ensure a proper reset sequence. The reset input should be held low for at least 10 ns to ensure that the device is properly reset.
• What is the recommended operating voltage range for the M74HC574M1R?
  The recommended operating voltage range for the M74HC574M1R is 2V to 6V, with a typical operating voltage of 5V. However, it's recommended to check the DC characteristics table in the datasheet for more information on the voltage range and its effects on the device's performance.
• How do I ensure data integrity when using the M74HC574M1R in a noisy environment?
  To ensure data integrity in a noisy environment, it's recommended to use proper PCB layout techniques, such as separating analog and digital signals, using ground planes, and adding decoupling capacitors. Additionally, consider using a voltage regulator to ensure a stable power supply, and consider adding error detection and correction mechanisms in your design.
• Can I use the M74HC574M1R in a 3.3V system?
  Yes, the M74HC574M1R can be used in a 3.3V system, but it's recommended to check the DC characteristics table in the datasheet to ensure that the device's performance meets your requirements at 3.3V. Additionally, ensure that the input and output voltage levels are compatible with your system's voltage levels.
