M74HC574B1R Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the M74HC574B1R is 25 MHz, but it can vary depending on the output load and the operating voltage.
  • It is recommended to power up the VCC pin before the VEE pin, and power down the VEE pin before the VCC pin to prevent latch-up and ensure proper operation.
  • The recommended output current for each output pin of the M74HC574B1R is 4 mA, but it can be as high as 8 mA for short periods of time.
  • Ensure that the operating voltage (VCC) is within the recommended range of 2V to 6V, and the operating temperature is within the range of -40°C to 125°C.
  • The OE pin is used to enable or disable the output of the M74HC574B1R. When OE is low, the outputs are enabled, and when OE is high, the outputs are disabled.
