The two amplifiers in LM3900 quad op amp form the bistable multivibrator. When the input is grounded, the output of one op amp becomes conduction, and the other op amp stops, and light-emitting diode indicates which op-amp is conduction at any given moment. Input is grounded again, the flip-flop's state flips over. This circuit is suitable for teaching demonstration in the classroom.
