CD74ACT174M Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD74ACT174M?
  The recommended operating voltage range for CD74ACT174M is 4.5V to 5.5V, although it can operate from 2V to 6V with reduced performance.
• How do I handle the unused inputs on the CD74ACT174M?
  Unused inputs on the CD74ACT174M should be tied to VCC or GND to prevent floating inputs, which can cause unpredictable behavior.
• What is the maximum clock frequency that the CD74ACT174M can handle?
  The maximum clock frequency that the CD74ACT174M can handle is 100 MHz, although this can vary depending on the specific application and operating conditions.
• Can I use the CD74ACT174M in a 3.3V system?
  Yes, the CD74ACT174M can be used in a 3.3V system, but the output voltage levels may not be fully compatible with 3.3V logic. A voltage translator or level shifter may be required.
• How do I ensure that the CD74ACT174M is properly powered up and initialized?
  To ensure proper power-up and initialization, the CD74ACT174M should be powered up slowly (dv/dt < 10V/μs) and the clock input should be held low during power-up. Additionally, the device should be reset after power-up using the reset input (if available).
