SN74HC574DBR datasheet by Texas Instruments

SN74HC574DBR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HC574DBR can handle?
  The maximum clock frequency of the SN74HC574DBR is 100 MHz.
• How do I ensure that the outputs are in a high-impedance state during power-up?
  To ensure that the outputs are in a high-impedance state during power-up, connect the OE (output enable) pin to VCC through a pull-up resistor.
• What is the recommended operating voltage range for the SN74HC574DBR?
  The recommended operating voltage range for the SN74HC574DBR is 2V to 6V.
• How do I handle the asynchronous inputs (e.g., preset and clear) during power-up?
  To handle asynchronous inputs during power-up, connect them to VCC or GND through a pull-up or pull-down resistor, respectively, to ensure a defined state.
• What is the maximum current that the SN74HC574DBR can sink or source?
  The maximum current that the SN74HC574DBR can sink or source is 25 mA per output pin.
