DESCRIPTION
PS2701-1, -2, and -4 are optically coupled isolators containing
a GaAs light emitting diode and a NPN silicon phototransistor.
Each is mounted in a plastic SOP (Small Outline Package) for
high density applications. This package has a shield effect to
cut off ambient light.
APPLICATIONS

equipment.
• AC LINE/DIGITAL LOGIC
• DIGITAL LOGIC INTERFACE
• TWISTED PAIR LINE RECEIVER
• TELEPHONE/TELEGRAPH LINE RECEIVER
• HIGH FREQUENCY POWER SUPPLY FEEDBACK
CONTROL
• RELAY CONTACT MONITOR
