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.
