SLL-50HF1A
Photon Activated Logic - “PAL”
Photo Detector with Inverter Logic Output
Features
Schmitt Trigger provides Hysteresis
Narrow receiving angle
Spectrally Matched to IRED
Wide VCC Range
Hermetically Sealed TO-18 style Package
Usable to 100 kHz
Very sensitive even in low light levels
Open collector Inverter output
VOH is high when input is dark
Description
The SLL-50HF 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 high dome lensed
package. The high dome lens provides a very high
sensitivity within a narrow field of view.
The hermetic
package provides high reliability in hostile environments.
The output NPN transistor will sink 16 mA at 400 mV.
Under a dark condition the output transistor is not
conducting. The Schmitt trigger provides immunity to noise
on either irradiance or VCC.
