GENERAL DESCRIPTION
ULN2803
是单片集成高耐压、大电流达林顿管阵列，电路内部包含八个独立的达林顿管驱动单路。
电路内部设计有钳位二极管，可用于驱动继电器、步进电机等电感性负载，将达林顿管并联可实现更高
的输出电流能力。该电路可广泛应用于继电器驱动、照明驱动、显示屏驱动
(LED)
、步进电机驱动和逻辑
缓冲器。
ULN2803
的每一路达林顿管串联一个
2.7K
的基极电阻，在
5V
的工作电压下可直接与
TTL/CMOS
电路连接，可直接处理标准逻辑缓冲器所处理的数据。

■
Any and all MSKSEMI Semiconductor products described or contained herein do not have specifications
that can handle applications that require extremely high levels of reliability, such as life-support systems,
aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your MSKSEMI Semiconductor representative nearest you
before using any MSKSEMI Semiconductor products described or contained herein in such applications.
■
MSKSEMI Semiconductor assumes no responsibility for equipment failures that result from using products
at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or
other parameters) listed in products specificationsof any andall MSKSEMI Semiconductor products described
