ADDITIONAL RESOURCES

1.What is 74HC21?

  • The 74HC21 is a 4-input dual AND gate. Clamp diodes are used as inputs. This allows for the use of current-limiting resistors to interface inputs to voltages greater than V CC.

2.Can the 74HC21 IC be used in conjunction with other digital circuits? 

  • Yes, the 74HC21 IC can be combined with other digital circuits such as microcontrollers, memory devices, and logic ICs to create a flexible and expandable system design.
