HCPL-073L Datasheet(HTML) 1 Page - AVAGO TECHNOLOGIES LIMITED |
1 / 12 page Description These high gain series couplers use a Light Emitting Di- ode and an integrated high gain photodetector to pro- vide extremely high current transfer ratio between input and output. Separate pins for the photodiode and out- put 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 photo-darlington operation. A base access terminal al- lows 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 mA of LED current. The HCPL-070L and HCPL-073L are surface mount de- vices packaged in an industry standard SOIC-8 footprint. The SOIC-8 does not require "through holes" in a PCB. This package occupies approximately one-third the foot- print area of the standard dual-in-line package. The lead profile is designed to be compatible with standard sur- face mount processes. Functional Diagram Features • 3.3V/5V Dual Supply Voltages • Low power consumption • High current transfer ratio • Low input current requirements – 0.5 mA • LVTTL/LVCMOS compatible output • Performance guaranteed over temperature 0°C to +70°C • Base access allows gain bandwidth adjustment • High output current – 60 mA • Safety approval, UL, IEC/EN/DIN EN 60747-5-2, CSA Applications • Ground isolate most logic families – LVTTL/LVCMOS • Low input current line receiver • High voltage insulation • EIA RS-232C line receiver • Telephone ring detector • V AC line voltage status indicator – low input power dissipation • Low power systems – ground isolation A 0.1 µF bypass capacitor connected between pins 8 and 5 is recommended. CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.
