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.
