DESCRIPTION
The H11LXM series has a high speed integrated circuit detector optically
coupled to a gallium-arsenide infrared emitting diode. The output incorpo-
rates 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.
