CD74HCT574E datasheet by Texas Instruments

CD74HCT574E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HCT574E can handle?
  The CD74HCT574E can handle clock frequencies up to 100 MHz.
• 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, such as a 74HCT series buffer, and to keep the output traces as short as possible.
• Can I use the CD74HCT574E with a 3.3V power supply?
  Yes, the CD74HCT574E is compatible with 3.3V power supplies, but it is recommended to use a 5V power supply for optimal performance.
• How do I handle the power-up and power-down sequences for the CD74HCT574E?
  It is recommended to power up the VCC pin before applying any input signals, and to power down the VCC pin after all input signals have been removed. This ensures that the device is properly initialized and avoids any potential latch-up conditions.
• What is the maximum capacitance that can be driven by the CD74HCT574E?
  The CD74HCT574E can drive up to 50 pF of capacitance per output pin, but it is recommended to keep the load capacitance as low as possible to ensure optimal performance.
