DESCRIPTION
PS2806-1 and PS2806-4 are optically coupled isolators con-
taining a GaAs light emitting diode and an NPN silicon
Darlington-connected phototransistor in a plastic SOP (Small
Out-Line Package) for high density applications. This device
has a shield effect to cut off ambient light.
APPLICATIONS
• PROGRAMMABLE LOGIC CONTROLLERS
• MEASURING INSTRUMENTS
• HYBRID IC
