M74HC244B1R Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the M74HC244B1R is 100 MHz.
  • Yes, the M74HC244B1R 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 should be connected to a logic low (GND) to enable the outputs. If left unconnected, the outputs will be in a high-impedance state.
  • The M74HC244B1R can sink or source up to 20mA per output pin.
  • Yes, the M74HC244B1R is compatible with 3.3V systems, but the output voltage will be limited to 3.3V.
