DESCRIPTION
The PS2707-1,-2 and -4 are optically coupled isolators con-
taining a GaAs light emitting diode and a NPN silicon
phototransistor. Each is mounted in a plastic SOP (Small Out-
Line Package) for high density applications. This package has
a shield effect to cut off ambient light.
APPLICATIONS
