Hola,
tengo una duda respecto al conexionado del 74HC151 para multiplicar las entradas digitales, mi circuito esta de esta manera:
Pero segun entiendo todos los pines del 74HC151 deben estar conectados de alguna manera. Siguiendo el codigo de:
http://www.arduino.cc/playground/Code/MUX151
faltaria conectar un pin de salida del 74HC.
Es necesario conectarlo? o puedo dejarlo de esta manera?
Saludos

Hola,
la salida que te queda es lo que en el argot se llama "la negada" que es la opuesta de la salida normal. No necesitaras conectarla.
Para mas informacion, dispones de la hoja de caracteristicas en:

Un saludo,
