MM74HC244WMX Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the MM74HC244WMX is 40 MHz.
  • Yes, the MM74HC244WMX is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
  • The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. Leaving it unconnected or connecting it to VCC will disable the outputs.
  • The MM74HC244WMX can sink or source up to 25mA per output pin, but it's recommended to limit the current to 10mA per pin to ensure reliable operation.
  • The MM74HC244WMX is rated for operation up to 125°C, but it's recommended to derate the device for temperatures above 85°C to ensure reliable operation.
