Manufacturer Name: onsemi

Category(s): Photodetectors

Description:

Plastic Silicon OPTOLOGIC Photosensor. ONSSPCISTNJZ8E4V; The QSE25x family are OPTOLOGIC ICs which feature a Schmitt trigger at output which provides hysteresis for noise immunity and pulse shaping. The basic building block of this IC consists of a photodiode, a linear amplifier, voltage regulator, Schmitt trigger and four output options. The TTL/LSTTL compatible output can drive up to ten TTL loads over supply currents from 4.5 to 16.0 Volts. The devices are marked with a color stripe for easy identification.
