SN74HCT574DW datasheet by Texas Instruments

SN74HCT574DW Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HCT574DW can handle?
  The maximum clock frequency of the SN74HCT574DW is 40 MHz.
• How do I ensure that the outputs are in a known state during power-up?
  To ensure that the outputs are in a known state during power-up, connect the OE (output enable) pin to GND or use an external pull-down resistor to force the outputs low during power-up.
• What is the recommended operating voltage range for the SN74HCT574DW?
  The recommended operating voltage range for the SN74HCT574DW is 4.5V to 5.5V.
• How do I handle the asynchronous inputs (e.g., preset, clear) during power-up?
  To handle asynchronous inputs during power-up, use a pull-up or pull-down resistor to ensure a known state, or use a power-on reset circuit to synchronize the inputs with the clock.
• What is the maximum current that the SN74HCT574DW can sink or source?
  The maximum current that the SN74HCT574DW can sink or source is 8mA per output pin.
