74LS90<\/span><\/h4>\n

Contador\u00a0por d\u00e9cadas y binario 74LS90. Puede contar en binario del 0 al 9 (BCD) y en biquinario. TTL<\/span><\/p>\n

Este circuito integrado consta de 2 contadores independientes uno de 1 bit y otro de 3 bits, utilizando los dos contadores internos podemos hacer que cuente de 0 a 9 aunque configurando los pines 2,3,6 y 7 con las salidas podemos hacer que no solo cuente en sistema decimal.<\/span><\/span><\/div>\n
En electr\u00f3nica<\/a> digital, un contador es un circuito secuencial<\/a> construido a partir de biestable<\/a> y puertas l\u00f3gicas<\/a> capaz de almacenar y contar los impulsos<\/a> (a menudo relacionados con una se\u00f1al de reloj), que recibe en la entrada<\/a> destinada a tal efecto, asimismo tambi\u00e9n act\u00faa como divisor de frecuencia. Normalmente, el c\u00f3mputo se realiza en c\u00f3digo binario<\/a>, que con frecuencia ser\u00e1 el binario natural<\/a> o el BCD natural<\/a> (contador de d\u00e9cadas).<\/span><\/div>\n
