CD54HC244F datasheet by Texas Instruments

CD54HC244F Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD54HC244F?
  The maximum frequency of operation for the CD54HC244F is 50 MHz.
• Can I use the CD54HC244F in a 5V system?
  Yes, the CD54HC244F 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 should be connected to GND to enable the outputs. If left floating, the outputs will be in a high-impedance state.
• What is the propagation delay of the CD54HC244F?
  The propagation delay of the CD54HC244F is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
• Can I use the CD54HC244F in a 3.3V system?
  Yes, the CD54HC244F 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.
