The device is meant as a photoelectric detector, in light barriers for example. The threshold is adjusted with an external resistor. After approx. 1 µs delay a photo current of sufficient magnitude creates a low signal which is compatible with CMOS and LSTTL levels at the output. The iC-VP can be utilised in a customised COB package as a multi-chip module for multi-channel scanning absolute encoders. TO18 metal can packages are available for singlechannel light barrier applications.
