CD74AC161E Frequently Asked Questions (FAQs)

  • The CD74AC161E can handle clock frequencies up to 100 MHz.
  • 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.
  • The propagation delay time of the CD74AC161E is typically around 10ns to 15ns, depending on the operating frequency and voltage.
  • 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.
  • 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.
