3) Por un puente angosto circulan cuatro lineas
ferroviarias. Por razones de seguridad se debe impedir que circulen dosformaciones
adyacentes. Para eso se han instalado dos señales de detension. Una en la
primera y otra en la tercer via. Diseñar un circuito digital lo mas
simplificado posible capaz de encender cada una de las señales cuando la
situación lo requiera.

6) Buscar y pegar la hoja de datos completa del circuito
integrado 4511 decodificador bcd a 7 segmentos de la familia cmos
7) Construir un circuito practico que permita verificar el
funcionamiento del circuito integrado 4511.Explicar la función de cada pin del
circuito
Pin number | Name | Purpose |
---|---|---|
1 | 2s | Input for the 2s bit from the binary counter |
2 | 4s | Input for the 4s bit from the binary counter |
3 | LT | Lamp test - when low, the chip takes all the segments on the display high (to test connections, etc.) |
4 | BI | Blanking input - when low, the chip does not output to the display - to conserve battery life, for instance |
5 | LE | Latch enable - latches on the current output when high (i.e. the inputs change the output when LE is low) |
6 | 8s | Input for the 8s bit from the binary counter |
7 | 1s | Input for the 1s bit from the binary counter |
8 | 0 V, VDD | The connection to the 0 V rail |
9 | E | Output for the seven-segment's E input |
10 | D | Output for the seven-segment's D input |
11 | C | Output for the seven-segment's C input |
12 | B | Output for the seven-segment's B input |
13 | A | Output for the seven-segment's A input |
14 | G | Output for the seven-segment's G input |
15 | F | Output for the seven-segment's F input |
16 | +9 V, VCC | The connection to the +9 V rail |
