CNZ1403B

Integrated Photosensors CNZ1402A/B, CNZ1403A/B Integrated Photosensors For contactless SW, object detection Overview CNZ1402A/B and CNZ1403A/B are photocouplers in which a high efficiency GaAs infrared light emitting diode as the light emitting element, and a photodiode and a signal processing circuit as a light detecting element are intergrated on a single chip. The two elements are arranged so as to face each other, and objects passing between them are detected. Features Built-in Schmitt circuit for strong noise-withstanding capability Large output current Open-collector output Output transistors turn on and off (two types) when light is shined CNZ1402A/CNZ1403A : Normally ON type CNZ1402B/CNZ1403B : Normally OFF type Absolute Maximum Ratings (Ta = 25˚C) Parameter Symbol Ratings Unit Reverse voltage (DC) VR 3 V Input (Light Forward current (DC) emitting diode) IF 50 mA Power dissipation PD*1 75 mW Output current IO 20 mA Output (Photo IC) Output voltage Supply vol...
