SN74HCT574DWR datasheet by Texas Instruments

SN74HCT574DWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HCT574DWR can handle?
  The maximum clock frequency of the SN74HCT574DWR is 40 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 SN74HCT574DWR?
  The recommended operating voltage range for the SN74HCT574DWR is 4.5V to 5.5V.
• How do I handle the asynchronous inputs (e.g., CLR, PRE) to prevent glitches?
  To handle asynchronous inputs, use a synchronous design approach by synchronizing the inputs to the clock signal using a flip-flop or a synchronizer circuit.
• What is the maximum capacitance that can be driven by the SN74HCT574DWR?
  The maximum capacitance that can be driven by the SN74HCT574DWR is 100 pF.
