Quiero hacer una simulación en LTSpice bu usando el modelo de especia de 74HC123. Utilicé el siguiente modelo de especias. Pero tomo los errores a continuación y no puedo hacer una simulación.
modelo SPICE:
* (DUAL) RETRIGGERABLE MONOSTABLE MULTIVIBRATOR
* Pulse Width Tw = 0.5 * R * C
* tpd R,A,B->Q 30n
* Tpulse 75n, C=0, Rext=5k
.SUBCKT 74HC123 A B CLR CGND RC Q QN VCC VGND
.param egain=1/{vcc1}
.param td5=1e-9*(5)*4.0/({vcc1}-0.5)*{speed1}
.param td2=1e-9*(2)*4.0/({vcc1}-0.5)*{speed1}
