Series−
DESCRIPTION
The PS2381-1 is an optically coupled isolator containing a GaAs light emitting diode and an NPN silicon
phototransistor.
This package is mounted in a plastic 4-LSOP (Long Mini-Flat Small Outline Package) for high density applications.
The package has shield effect to cut off ambient light.
FEATURES
