SN74HC574NSR Frequently Asked Questions (FAQs)

  • The SN74HC574NSR can handle clock frequencies up to 100 MHz.
  • To ensure that the outputs are in a high-impedance state during power-up, connect the OE (output enable) pin to VCC or use an external pull-up resistor to VCC.
  • The SN74HC574NSR can sink or source up to 25 mA of current per output pin.
  • The CLR input is an asynchronous active-low input that clears the internal registers. It should be tied to VCC through a pull-up resistor if not used.
  • The recommended operating voltage range for the SN74HC574NSR is 2 V to 6 V, with a typical operating voltage of 5 V.
