HOA7720 Description
The HOA7720/7730 Series consists of an infrared emitting diode facing an Optoschmitt detector encased in a black thermoplastic housing. The photodetector consists of a photodiode, amplifier, voltage regulator and Schmitt trigger with either of two output configurations: Totem pole (HOA7720-M11) Open collector (HOA7730-M11) The totem pole output is well-suited for applications which require fast transition times.
