MM74HCT574WM Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the MM74HCT574WM is 4.5V to 5.5V.
  • To ensure reliable data retention, the chip select (CS) pin should be held low during power-down, and the VCC pin should be ramped down slowly to prevent data loss.
  • The maximum clock frequency supported by the MM74HCT574WM is 10 MHz.
  • Yes, the MM74HCT574WM can be used in a 3.3V system, but the input and output voltage levels should be adjusted accordingly to ensure proper operation.
  • The VCC pin should be powered up before the clock (CLK) pin, and the VCC pin should be powered down after the clock (CLK) pin to prevent data loss and ensure reliable operation.
