DESCRIPTION
The PS2705-1, PS2705-2, PS2705-4 are optically coupled isolators containing two GaAs light emitting diodes and
an NPN silicon phototransistor.
These packages are SOP (Small Outline Package) type and have shield effect to cut off ambient light.
They are designed for high density mounting applications.
FEATURES
AC input response
High isolation voltage (BV = 3 750 Vr.m.s.)
High current transfer ratio (CTR = 100 % TYP.)
SOP (Small Outline Package) type
