SN74LS244NE4 Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74LS244NE4 is 35 MHz.
  • No, the SN74LS244NE4 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 SN74LS244NE4 can sink up to 24 mA and source up to -15 mA per output pin.
  • No, the SN74LS244NE4 is not designed to be used as a level translator. It is a buffer/driver device and is not intended to translate voltage levels.
