CD74HC574M datasheet by Texas Instruments

CD74HC574M Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HC574M can handle?
  The CD74HC574M can handle clock frequencies up to 100 MHz.
• How do I ensure that the CD74HC574M is properly powered?
  The CD74HC574M requires a power supply voltage (VCC) of 2.0 V to 6.0 V, and it is recommended to decouple the power supply with a 0.1 μF capacitor.
• What is the maximum current that the CD74HC574M can sink or source?
  The CD74HC574M can sink or source up to 25 mA of current per output pin.
• How do I handle the asynchronous reset (R) input?
  The asynchronous reset (R) input should be tied to VCC through a pull-up resistor (e.g., 1 kΩ) to ensure proper operation.
• What is the purpose of the output enable (OE) input?
  The output enable (OE) input is used to enable or disable the outputs of the CD74HC574M. When OE is low, the outputs are enabled, and when OE is high, the outputs are high-impedance.
