Alternative Logic Gates | Bubbled Gates

Alternative Logic Gates-

 

  • As the name suggests, Alternative logic gate is a logic gate that can be used in the absence or during the unavailability of the given logic gate to produce the same output.
  • Alternative logic gates are also called as Alternate Gates.

List of Alternative Logic Gates-

 

 

NOTE-

 

Because alternative logic gates contain bubbles in them, so they are also called as “Bubbled Gates“.

 

Rules for drawing Alternative Logic Gates-

 

Rules for AND, NAND, OR and NOR gates-

 

  • Both the inputs of alternative gate will have bubbles (which represents NOT gate).
  • For AND structured original gate, alternative gate will be OR structured.
  • For OR structured original gate, alternative gate will be AND structured.
  • If bubble is present at the output of original gate, then no bubble will be present at the output of alternative gate and vice-versa.

 

Rules for EX-OR and EX-NOR gates-

 

  • One of the inputs of alternative gate will have a bubble (which represents NOT gate).
  • For EX-OR structured original gate, alternative gate will be EX-NOR structured.
  • For EX-NOR structured original gate, alternative gate will be EX-OR structured.
  • If bubble is present at the output of original gate, then no bubble will be present at the output of alternative gate and vice-versa. (same as above)
