6N137数据手册

6N137光耦合器是一款用于单通道的高速光耦合器，其内部有一个850nm波长AlGaAsLED和一个集成检测器组成，其检测器由一个光敏二极管、高增益线性运放及一个肖特基钳位的集电极开路的三极管组成。

具有温度、电流和电压补偿功能，高的输入输出隔离，L S T T L/T T L兼容，高速(典型为10M B d)，5m A的极小输入电流。

特性：①转换速率高达10MBit/s;②摆率高达10kV/us;③扇出系数为8;④逻辑电平输出;⑤集电极开路输出;工作参数：最大输入电流，低电平：250uA最大输入电流，高电平：15mA最大允许低电平电压(输出高)：最大允许高电平电压：Vcc最大电源电压、输出：扇出(TTL负载)：8个(最多)工作温度范围：-40°Cto+85°C典型应用：高速数字开关，马达控制系统和A/D转换等6N137光耦合器的内部结构、管脚如图1所示。

？6N137光耦合器的真值如表1所示：6N137光耦合器的真值表输入使能输出H H LL H HH L H需要注意的是，在6N137光耦合器的电源管脚旁应有—个的去耦电容。

在选择电容类型时，应尽量选择高频特性好的电容器，如陶瓷电容或钽电容，并且尽量靠近6N137光耦合器的电源管脚；另外，输入使能管脚在芯片内部已有上拉电阻，无需再外接上拉电阻。

6N137光耦合器的使用需要注意两点：第一是6N137光耦合器的第6脚Vo输出电路属于集电极开路电路，必须上拉一个电阻；第二是6N137光耦合器的第2脚和第3脚之间是一个LED，必须串接一个限流电阻6N137的内部结构原理如下图所示，信号从脚2和脚3输入，发光二极管发光，经片内光通道传到光敏二极管，反向偏置的光敏管光照后导通，经电流-电压转换后送到与门的一个输入端，与门的另一个输入为使能端，当使能端为高时与门输出高电平，经输出三极管反向后光电隔离器输出低电平。

当输入信号电流小于触发阈值或使能端为低时，输出高电平，但这个逻辑高是集电极开路的，可针对接收电路加上拉电阻或电压调整电路。
