SLL-50HF2A
Photon Activated Logic - “PAL”
Photo Detector with Inverter Logic Output
Features
Supply voltage range 4.5V to 18V
Schmitt Trigger provides Hysteresis
Flat lens with wide receiving angle
Spectrally matched to 880nm IRED
Wide VCC Range
Hermetically Sealed TO-18 style Package
Very sensitive even in low light levels
Open collector Inverter output
VOH is high when input is dark
Description
The SLL-50HF2A series detector consists of a monolithic
photodiode, voltage regulator, hysteresis amplifier, and NPN
open collector output transistor on a single chip mounted in
a hermetically sealed TO-18 flat lensed package. The flat
lens provides a very high sensitivity within a wide field of
view.
The hermetic package provides high reliability in
hostile environments.
Under a dark condition the output
transistor is not conducting.
The Schmitt trigger provides
immunity to noise on either irradiance or VCC.
