SN54LS221J Frequently Asked Questions (FAQ)

  • The maximum clock frequency of the SN54LS221J is 35 MHz.

  • The SN54LS221J 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 SN54LS221J can sink up to 24mA and source up to 12mA 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 SN54LS221J is 10ns, but it can vary depending on the operating conditions and load capacitance.
