CD74AC161M Frequently Asked Questions (FAQs)

  • The CD74AC161M can handle clock frequencies up to 100 MHz.
  • To ensure proper synchronization, the CD74AC161M should be clocked on the rising edge of the clock signal, and the clock signal should be clean and free of noise.
  • The CD74AC161M can tolerate input voltages up to 7V, but it is recommended to operate within the recommended operating conditions of 4.5V to 5.5V for optimal performance.
  • To handle metastability issues, it is recommended to use synchronous design techniques, such as using a synchronizer circuit or a FIFO buffer, to ensure that the data is properly synchronized with the clock signal.
  • Yes, the CD74AC161M can be used in a 3.3V system, but it is recommended to use a voltage regulator to ensure that the voltage supply is within the recommended operating range of 4.5V to 5.5V.
