Data Sheet ACPL-K70A/K73A Low Input Current, High Current Gain, LVTTL, LVCMOS Optocoupler Description Table 1: Truth Table These high gain series couplers use a light-emitting diode LED Output (LED) and an integrated high gain photodetector to provide ON L an extremely high current transfer ratio between input and OFF H output. Separate pins for photodiode and output stage result in LVTTL-compatible saturation voltages and high-speed A 0.1-F bypass capacitor must be connected between pins operation. Where desired, the V and V terminals may be CC O V and GND. CC tied together to achieve conventional photo-darlington operation. A base access terminal allows a gain bandwidth Features adjustment to be made. 3.3V/5V dual supply voltages These optocouplers are for use in LVTTL/LVCMOS or other Low power consumption low-power applications. High current transfer ratio Low input current requirements: 0.04 mA The ACPL-K70A and ACPL-K73A are surface-mount Stretched SO8 package devices that are packaged in an industry-standard stretched LVTTL/LVCMOS compatible output SOIC-8 footprint. Guaranteed performance within the temperature range 40C to +105C The stretched SOIC-8 does not require through holes in a PCB. Base access allows gain bandwidth adjustment High output current: 60 mA Figure 1: Functional Diagram Worldwide Safety Approval: UL1577 recognized: 5000 V /1 min rms CSA approval IEC 60747-5-5 approval for reinforced insulation Applications EIA RS-232C/low input current line receiver Low power systems: ground isolation Line voltage status indicator low input power dissipation CAUTION Take normal static precautions in handling and assembling this component to prevent damage and/or degradation that may be induced by ESD.
