Plastic Silicon OPTOLOGIC® Photosensor
Features
Description
■ Bipolar silicon IC
The QSE25x 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.
■ Package type: Sidelooker
■ Medium wide reception angle, 50°
■ Package material and color: black epoxy
■ Daylight filter
■ High sensitivity
■ Direct TTL/LSTTL interface

Absolute Maximum Ratings (TA = 25°C unless otherwise specified)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
