Description

The QSE15X 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.
