The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of SN74LS221N, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
SN74LS221N Frequently Asked Questions (FAQ)
-
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.
