DESCRIPTION
NEC's PS2861H-1 is an optically coupled isolator containing
a GaAs light emitting diode and an NPN silicon phototran-
sistor. This is a half-pitch SOP (Small Out-line Package) for
high density mounting surface mountable applications. This
is ideal for implementing highly isolated interface, 3kVrms in
accordance with international safety standards.
APPLICATION
• SWITCHING MODE POWER SUPPLY
• MODEM, FAX AND TELEPHONE
• DATA INTERFACE OF DIFFERENT POTENTIALS
