Biestable con 555 y 4013 CIR4390S (CIR4390S)

Written by: Newton C. Braga
Category: Banco de circuitos

 

    A cada reloj del 555 (transición negativa) el 4013 (flip-flop) cambia de estado accionando el relé o apagándolo, dependiendo de su condición anterior. La constante de tiempo dada por el resistor de 47 k ohmios y por el capacitor de 100 nF determina el tiempo mínimo entre dos pulsos de control. El relé utilizado depende de la tensión de alimentación y se recomiendan los tipos sensibles de 6 o 12 V. Dado que el circuito integrado 4013 tiene dos flip-flops disponibles y esta configuración sólo se aprovecha, el otro puede utilizarse con otros fines.
