CONCEPTO BÁSICO:
Esto funciona si está utilizando compuertas y limita la corriente de salida de las compuertas para que su voltaje de salida no caiga por debajo del voltaje de umbral bajo de las entradas.
TUCIRCUITO
AquíestásucircuitoysulistadecircuitosenLTspiceparaquepuedasimularlo.
S1yS2correspondenalosinterruptoresdelaforma"A" que has mostrado, pero LTspice no tiene interruptores operados manualmente, así que los he mostrado como relés.
El flip-flop funciona un poco, pero observe que los LED están en paralelo con las uniones de emisor de base, por lo que nunca verán más de unos 800 milivoltios, tops, a través de ellos, lo que significa que nunca se encenderán.
Examine alrededor y encontrará otras discrepancias ...
