'''ULN2803''' es un circuito integrado [[matriz de transistores]] [[Darlington]] [[NPN]].&lt;br /&gt;
&lt;br /&gt;
==Descripción==&lt;br /&gt;
&lt;br /&gt;
[[ULN2803]] es un [[circuito integrado]] que es una [[matriz]] de ocho [[transistores Darlington]] NPN configurados en [[emisor común]], cada uno de estos ocho transistores es capaz de manejar una corriente de 500mA y un voltaje de 50V. Además para manejar cargas inductivas cuenta con [[diodos]] de protección de voltaje inverso con conexión de cátodo común. Sus entradas son compatibles con los [[circuitos lógicos]] [[TTL]] y [[CMOS]] de 5V, además puede ser conectado a cualquier placa [[Arduino]].  Su [[encapsulado]] es plástico de tipo [[DIP-18]].&lt;br /&gt;
&lt;br /&gt;
== Principales características ==&lt;br /&gt;
&lt;br /&gt;
Voltaje colector emisor: 50V&lt;br /&gt;
&lt;br /&gt;
Salidas de 500mA máximos en modo continuo y 600mA en pico.&lt;br /&gt;
&lt;br /&gt;
Los transistores pueden ser conectados en paralelo para mayor capacidad de corriente.&lt;br /&gt;
&lt;br /&gt;
Potencia de disipación máxima: 1.47W&lt;br /&gt;
&lt;br /&gt;
Resistencia de entrada a la base: 2.7kΩ&lt;br /&gt;
&lt;br /&gt;
Rango de temperatura de operación: -65 a 150ºC&lt;br /&gt;
&lt;br /&gt;
==Aplicaciones==&lt;br /&gt;
&lt;br /&gt;
Dentro de sus variadas aplicaciones tenemos: controlador de [[relés]], [[servomotores]], motores paso a paso, lámparas, [[solenoides]], pantallas [[Led]] y bombillas de [[filamentos]].&lt;br /&gt;
