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.

FEATURES

• Bipolar silicon IC

•Package type: Sidelooker

• Medium wide reception angle, 50°

•Package material and color: black epoxy

• Matched emitter: QEE113/QEE123

•Daylight ﬁlter

• High sensitivity

•Direct TTL/LSTTL interface
