L293D集成电路说明 描述

The L293D is a monolithic integrated high voltage,

high current four channel vriver designed to accept

standard DTL or TTL logic levels and drive induc-tive

loads (such as relays solenoides, DC and

stepping motors) and switching power transistors.

L293D 是单块集成电路，高电压，高电流，四通道驱动，

设计用来接受DTL或者TTL逻辑电平，驱动感性负载(比如

继电器，直流和步近马达)，和开关电源晶体管。

To simplify use as two bridges is pair of channels

is equiped with an enable input. Aseparate supply

innput is provited formthe logic, allowing operation

at a low voltage and internal clamp diodes are

included.

简单的使用是作为2个桥，一对通道连接起来有一个使能输入
