一文看懂uln2803和uln2003区别描述一、ULN2003介绍ULN2003是高耐压、大电流复合晶体管阵列，由七个硅NPN复合晶体管组成，每一对达林顿都串联一个2.7K的基极电阻，在5V的工作电压下它能与TTL和CMOS电路直接相连，可以直接处理原先需要标准逻辑缓冲器来处理的数据。
ULN2003特点：ULN2003的每一对达林顿都串联一个2.7K的基极电阻，在5V的工作电压下它能与TTL和CMOS电路直接相连，可以直接处理原先需要标准逻辑缓冲器来处理的数据。
ULN2003工作电压高，工作电流大，灌电流可达500mA，并且能够在关态时承受50V的电压，输出还可以在高负载电流并行运行。
ULN2003采用DIP—16或SOP—16塑料封装。
ULN2003引脚及功能：引脚1：CPU脉冲输入端，端口对应一个信号输出端。
引脚2：CPU脉冲输入端。
引脚3：CPU脉冲输入端。

引脚6：CPU脉冲输入端。
引脚7：CPU脉冲输入端。
引脚8：接地。
引脚9：该脚是内部7个续流二极管负极的公共端，各二极管的正极分别接各达林顿管的集电极。
用于感性负载时，该脚接负载电源正极，实现续流作用。
如果该脚接地，实际上就是达林顿管的集电极对地接通。
引脚10：脉冲信号输出端，对应7脚信号输入端。
引脚11：脉冲信号输出端，对应6脚信号输入端。
引脚12：脉冲信号输出端，对应5脚信号输入端。
引脚13：脉冲信号输出端，对应4脚信号输入端。
引脚14：脉冲信号输出端，对应3脚信号输入端。
引脚15：脉冲信号输出端，对应2脚信号输入端。
引脚16：脉冲信号输出端，对应1脚信号输入端。
ULN2003作用：ULN2003是大电流驱动阵列，多用于单片机、智能仪表、PLC、数字量输出卡等控制电路中。
可直接驱动继电器等负载。
输入5VTTL电平，输出可达500mA/50V。
ULN2003是高耐压、大电流达林顿系列，由七个硅NPN达林顿管组成。
