DESCRIPTION
NEC's PS2861-1 is an optically coupled isolator containing a
GaAs light emitting diode and an NPN silicon phototransistor.
This device's insulation thickness of 0.4 mm meets BSI's
supplementary insulation requirements. This package is
mounted in a plastic SOP (Small Out-line Package) for high
density applications and has a shield effect to cut off ambient
light.
APPLICATIONS
• MODEM
• PROGRAMMABLE LOGIC CONTROLLERS
• POWER SUPPLY
