SN74HCT574PW Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HCT574PW is 40 MHz.
  • 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 ground.
  • The recommended operating voltage range for the SN74HCT574PW is 4.5V to 5.5V.
  • Yes, the SN74HCT574PW can be used in a 3.3V system, but the output voltage will be limited to 3.3V. Additionally, the input voltage thresholds may not be compatible with 3.3V logic levels.
  • The asynchronous reset (RST) input should be tied to VCC through a pull-up resistor to ensure that the device is properly reset during power-up.
