Single Channel, High Speed Optocouplers
Dec.2008
Description
These high gain series couplers use a light
emitter diode and an integrated high gain
photo detector to provide 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.
Features
High current transfer ratio – 2000%
typical.
Low input current requirements – 0.5mA
High output current – 60mA
CTR guarantee – 0~70℃.
Instantaneous common mode rejection
10KV/μsec
TTL compatible output – 0.1V V
OL
