DESCRIPTION
The H11NX-M series has a high speed integrated circuit detector optically
coupled to an AlGaAs infrared emitting diode. The output incorporates a
Schmitt trigger, which provides hysteresis for noise immunity and pulse s
haping. The detector circuit is optimized for simplicity of operation and utilizes
an open collector output for maximum application flexibility.
