CD74AC161E datasheet by Texas Instruments

CD74AC161E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74AC161E can handle?
  The CD74AC161E can handle clock frequencies up to 100 MHz.
• How do I ensure that the CD74AC161E is properly powered?
  The CD74AC161E requires a power supply voltage (VCC) of 2.0V to 6.0V, and it is recommended to decouple the power supply with a 0.1uF capacitor to reduce noise and ensure stable operation.
• What is the propagation delay time of the CD74AC161E?
  The propagation delay time of the CD74AC161E is typically around 10ns to 15ns, depending on the operating frequency and voltage.
• Can I use the CD74AC161E in a 3.3V system?
  Yes, the CD74AC161E is compatible with 3.3V systems, but it is recommended to check the voltage tolerance of the device and ensure that it meets the system's voltage requirements.
• How do I handle the asynchronous reset input (RST) of the CD74AC161E?
  The asynchronous reset input (RST) should be tied to VCC through a pull-up resistor (typically 1kΩ to 10kΩ) to ensure that the device is properly reset. The RST input should be driven low to reset the device, and then released to allow normal operation.
