SN74LS221N Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS221N is 35 MHz.
  • The SN74LS221N 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 reduce noise and ensure stable operation.
  • The SN74LS221N can sink or source up to 24mA 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 low-going pulse on CLR will reset the device.
  • The typical propagation delay of the SN74LS221N is 10ns, but it can vary depending on the operating conditions and load capacitance.
