SN74LS244DW Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74LS244DW is 30 MHz.
  • No, the SN74LS244DW is a 5V device and is not compatible with 3.3V systems. You may need to use a level translator or a different device that is compatible with 3.3V systems.
  • The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (connected to GND) and disabled when OE is high (connected to VCC). You can tie OE to GND if you want the outputs to be always enabled.
  • The SN74LS244DW can sink up to 24 mA and source up to -15 mA per output pin.
  • The SN74LS244DW is rated for operation up to 70°C. If you need to operate the device in a higher temperature environment, you may need to derate the device or use a different device that is rated for higher temperatures.
