CD74ACT109M Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD74ACT109M?
  The recommended operating voltage range for the CD74ACT109M is 4.5V to 5.5V, although it can operate as low as 3.5V with reduced performance.
• How do I handle the output enable (OE) pin in my design?
  The output enable (OE) pin should be connected to a logic signal that is low (0V) when the outputs are desired to be enabled, and high (VCC) when the outputs are desired to be disabled (high-impedance state).
• What is the maximum clock frequency that the CD74ACT109M can handle?
  The maximum clock frequency that the CD74ACT109M can handle is 100 MHz, although this may vary depending on the specific application and operating conditions.
• How do I ensure that the CD74ACT109M is properly powered and decoupled?
  It is recommended to use a 0.1uF ceramic capacitor between the VCC pin and GND pin, and to ensure that the power supply is stable and well-regulated to prevent noise and oscillations.
• Can I use the CD74ACT109M in a 3.3V system?
  Yes, the CD74ACT109M can be used in a 3.3V system, but the output voltage levels may not be as high as those in a 5V system, and the device may not be as fast or have as much drive capability.
