SN74AC244DBR datasheet by Texas Instruments

SN74AC244DBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74AC244DBR?
  The maximum operating frequency of the SN74AC244DBR is 100 MHz.
• Can I use the SN74AC244DBR in a 5V system?
  Yes, the SN74AC244DBR is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
• How do I handle the output enable (OE) pin?
  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.
• What is the maximum current that the SN74AC244DBR can sink or source?
  The SN74AC244DBR can sink or source up to 24 mA of current per output pin.
• Can I use the SN74AC244DBR in a 3.3V system?
  Yes, the SN74AC244DBR is compatible with 3.3V systems, but the output voltage will be limited to 3.3V. Ensure that the input signals are also 3.3V-compatible.
