QXH11LX
概述 Description
QXH11LX 系列器件具备 GaAs 红外发射二极管，该二极管光学耦合到高速集成电路探测器。输出探测器包含施密
特触发器，为噪声免疫和脉冲整形提供了滞后效应。
The QXH11LX series of devices each consist of a GaAs infrared emitting diode optically coupled a high speed
integrated circuit detector. The output detector incorporates a Schmitt trigger, which provides hysteresis for
noise immunity and pulse shaping.
