QSE159 Description

Short technical summary and product information.

The QSE159 from On Semiconductor is a versatile OPTOLOGIC IC photosensor designed for various applications requiring light detection with logic output. It incorporates a photodiode, linear amplifier, voltage regulator, and a Schmitt trigger for enhanced noise immunity and pulse shaping.

 

This device operates within a temperature range of -40°C to 85°C and features a medium wide reception angle of 50°. The output type is an open collector inverter, compatible with TTL/LSTTL interfaces. It is housed in a black epoxy sidelooker package.

 

Key electrical characteristics include a supply voltage range of 4.0V to 16V, an output current capability of up to 50mA, and a maximum output voltage of 35V. The photosensor has a typical propagation delay of 6.0ns and output rise/fall times of 100ns.

 

This component is suitable for applications where reliable light detection and logic-level signaling are required. Its direct TTL/LSTTL interface simplifies integration into digital systems.
