FAIRCHILD SEMICONDUCTOR H11L3M 光耦合器,施密特触发器
The H11L3-M is a 1-channel 6-pin H11LXM series Schmitt Trigger Output Optocoupler has a high-speed integrated circuit detector optically coupled to a gallium-arsenide infrared emitting diode. The output incorporates a Schmitt trigger, which provides hysteresis for noise immunity and pulse shaping. The detector circuit is optimized for simplicity of operation and utilizes an open collector output for maximum application flexibility.
