DESCRIPTION
The PS2765-1 is an optically coupled isolator containing GaAs
light emitting diodes and an NPN silicon phototransistor. 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
• HYBRID IC
• PROGRAMMABLE LOGIC CONTROLLERS
• POWER SUPPLY
