Data Sheet
Features Low power consumption High current transfer ratio Low input current requirements – 0.5 mA Description These high gain series couplers use a Light Emitting Diode and an integrated high gain photodetector to provide extremely high current transfer ratio between input and output. Separate pins for the photodiode and output stage result in LVTTL compatible saturation voltages and high speed operation. Where desired, the VCC and VO terminals may be tied together to achieve conventional photoFunctional Diagram darlington operation. A base access terminal allows a gain bandwidth adjustment to be made. These optocouplers are for use in LVTTL/LVCMOS or other low power applications. A 400% minimum current transfer ratio is guaranteed over 0 to +70C operating range for only 0.5 mA of LED current. LVTTL/LVCMOS compatible output Performance guaranteed over temperature 0C to +70C Base access allows gain bandwidth adjustment High output current – 60 mA Safety approval, UL, VDE, CSA (pending) Applications Ground isolate most logic families – LVTTL/LVCMOS Low input current line receiver High voltage insulation EIA RS-232C line receiver
