QSE157 QSE158 QSE159 Light Output On Off On Off On Off On Off High Low Low High High Low Low High DESCRIPTION The QSE15X 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.
