SN74HCT574DBR datasheet by Texas Instruments

SN74HCT574DBR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HCT574DBR can handle?
  The maximum clock frequency of the SN74HCT574DBR is 40 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
• How do I ensure that the SN74HCT574DBR is properly powered and decoupled?
  To ensure proper power and decoupling, use a high-quality power supply, decouple the VCC pin with a 0.1 μF ceramic capacitor, and use a 10 μF electrolytic capacitor for bulk decoupling. Also, ensure that the power supply rails are clean and free of noise.
• What is the recommended operating temperature range for the SN74HCT574DBR?
  The recommended operating temperature range for the SN74HCT574DBR is -40°C to 125°C, but it can vary depending on the specific application and the environment in which it is used.
• How do I handle the output enable (OE) pin during power-up and power-down sequences?
  During power-up and power-down sequences, it is recommended to keep the OE pin in a high-impedance state (i.e., OE = high) to prevent unwanted output transitions. Once the power supply is stable, the OE pin can be driven low to enable the outputs.
• What is the maximum current that the SN74HCT574DBR can sink or source?
  The maximum current that the SN74HCT574DBR can sink or source is 25 mA per output pin, but it is recommended to limit the current to 10 mA per pin to ensure reliable operation.
