DESCRIPTION
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。
