CD74HC4538M datasheet by Texas Instruments

CD74HC4538M Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC4538M?
  The maximum frequency of operation for the CD74HC4538M is 40 MHz.
• Can I use the CD74HC4538M in a 5V system?
  Yes, the CD74HC4538M 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 propagation delay of the CD74HC4538M?
  The propagation delay of the CD74HC4538M is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
• Can I use the CD74HC4538M in a 3.3V system?
  Yes, the CD74HC4538M is compatible with 3.3V systems, but the output voltage levels may not be as high as in a 5V system. Ensure that the receiving device can handle the reduced voltage levels.
