Ce montage est monte en regime de commutation;donc on vas s'exprimer en terme de 0 et 1[0=0volt Et 1=+Vcc].la lampe en sortie ne s'allume que si limpulsion"I" connectee aux entrees negatives des 2 AOP atteint une tension situee dans la marge 1/3Vcc<Vi>2/3Vcc[Vi:tension impulsion ];et elle s'etteint lorsque Vi<1/3Vcc<2/3Vcc ou Vi>1/3Vcc>2/3Vcc.
