Photocoupler
These high gain series couplers use a AlGaAs
LED and an integrated high gain photo
detector to provide an extremely high current
transfer ratio between input and output.
Separate pins for the photodiode and output
stage result in TTL compatible saturation
voltage and high speed operation. Where
desired the Vcc and Vo terminals may be tied
together to achieve conventional photo
Darlington operation. A base access terminal
allows a gain bandwidth adjustment to be
made.
