SN74221N Frequently Asked Questions (FAQs)

  • The SN74221N can handle clock frequencies up to 10 MHz.
  • The SN74221N requires a single 5V power supply, and it's recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper power supply decoupling.
  • The SN74221N can sink or source up to 16mA of current per output pin.
  • The CLR input should be tied to VCC through a pull-up resistor (e.g. 1kΩ) to ensure that the device is not inadvertently reset. A capacitor (e.g. 100nF) can also be added in parallel to filter out noise.
  • The propagation delay of the SN74221N is typically around 10-15ns, but this can vary depending on the specific application and operating conditions.
