Agilent HCPL-270L/ 070L/273L/073L Low Input Current High Gain LVTTL/LVCMOS patible 3.3 V Optocouplers Data Sheet 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 patible saturation voltages 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. These optocouplers are for use in LVTTL/LVCMOS or other low power applications. A 400% minimum current transfer ratio is guaranteed over 0 to +70˚C operating range for only 0.5 m A of LED current.
