242 : Demultiplexor NAND

  • Author: Mauricio Caballero Hernández - Alejandro Duran Morales - Marvin Yahir Salamanca Ramirez - Kevin Ortiz Sarate
  • Description: Demultiplexor de 3 entradas independientes y 3 entradas de dirección que arrojan valore logicos de 0 y 1 en 8 salidas diferentes, constituido por compuertas NAND y NOT, imitando el comportamiento de un LS138
  • GitHub repository
  • Clock: 0 Hz

How it works

Introduciendo un total de 6 señales en el circuito se puede arrojar una señal negada (un valor de 0 logico) en una de las 8 salidas disponibles. Las primeras 3 entradas dentro del circuito son clasificadas como entradas de dirección y se encargan de configurar el Demultiplexor, los otros 3 puertos de entrada admiten valores de entrada independientes que terminan por infliur en las entradas de las compuertas logicas NAND y eso enconjunto permite que se arrojen valores logicos, predominando los estados altosen 7 de 8 salidas, mientras que la salida restante arroja un valor logico de 0 (lo cual admite un total de 8 combinaciones posibles con resultados diferentes). Todo el cuerpo del Demultiplexor esta conformado por compuertas NAND de 4 entradas y su demanda de compuertas NOT es minima en comparacion.

How to test

Para probar el circuito es necesario utilizar un dip switch de 6 entradas donde las primeras 3 posiciones conformaran las entradas de dirección (E0-E2) mientras que las posiciones 4 a 6 seran las entradas independientes (A0-A2). En su estado natural, (sin señales de entrada más que la E0), se arrojara el estado bajo a O0, Para arrojar un valor de 0 a la salida O1 es necesario mantener activa la entrada de direccion E0 y la entrada independiente A0. Para cambiar a la salida O2 se mantiene la entrada de dirección E0 y la entrada A1. Para cambiar a la salida O3 se mantiene la entrada de dirección E0 y la entrada A0 + A1. Para cambiar a la salida O4 se mantiene la entrada de dirección E0 y la entrada A2. Para cambiar a la salida O5 se mantiene la entrada de dirección E0 y la entrada A0 + A2. Para cambiar a la salida O6 se mantiene la entrada de dirección E0 y la entrada A1 + A2. Para cambiar a la salida O7 se mantiene la entrada de dirección E0 y la entrada A0 + A1 + A2. Para que todas las salidas arrojen un valor logico de 1 se necesita que se activen las entradas E1 + E2.
