1 / 7 page tm August 2012 ©2004 Fairchild Semiconductor Corporation www.fairchildsemi.com QSE256, QSE257, QSE258, QSE259 Rev. 1.0.1 QSE256, QSE257, QSE258, QSE259 Plastic Silicon OPTOLOGIC® Photosensor Features ■ Bipolar silicon IC ■ Package type: Sidelooker ■ Medium wide reception angle, 50° ■ Package material and color: black epoxy ■ Daylight filter ■ High sensitivity ■ Direct TTL/LSTTL interface Description The QSE25x family are OPTOLOGIC® ICs which feature a Schmitt trigger at output which provides hyster- esis 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 out- put 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.
