They provide extremely high current transfer ratio and excellent inputoutput common mode transient immunity. A separate pin for the photodiodes and first gain stages (VCC) permits lower output saturation voltage and higher speed operation than possible with conventional photodarlington type optocouplers. In addition, VCC may be as low as 1.6 V Functional Diagram ANODE 1 1 8 VCC CATHODE 1 2 7 VO1 CATHODE 2 3 6 VO2 ANODE 2 4 TRUTH TABLE LED VO ON LOW OFF HIGH 5 GND *5000 V rms/1 minute withstand voltage rating is for Option 020 (HCPL-2730, HCLP-2731) products only. A 0.1 µF bypass capacitor connected between pins 5 and 8 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. 1-108 5965-3597E without adversely affecting the parametric performance. These dual channel optocouplers are available in an 8-Pin DIP and in an industry standard SO-8 package. The following is a cross reference table listing the 8-Pin DIP part number and the electrically equivalent SOIC-8 part number. 8-Pin DIP SO-8 HCPL-2730 HCPL-0730 HCPL-2731 HCPL-0731 The SO-8 does not require “through holes” in a PCB. This package occupies approximately one-third the footprint area of the standard dual-in-line package. The lead profile is designed to be compatible with standard surface mount processes. Guaranteed operation at low input currents and the high current transfer ratio (CTR) reduce the magnitude and effects of CTR degradation. The outstanding high temperature performance of this split Darlington type output amplifier results from the inclusion of an integrated emitter-base bypass resistor which shunts photodiode and first stage leakage currents to ground. The HCPL-2731/0731 have a 400% minimum CTR at an input current of only 0.5 mA making it ideal for use in low input current applications such as MOS, CMOS, and low power logic interfacing or RS232C data transmission systems. In addition, the high CTR and high output current capability make this device extremely useful in applications where a high fanout is required. Compatibility with high voltage CMOS logic systems is guaranteed by the 18 V VCC and VO specifications and by testing output high leakage (IOH) at 18 V. The HCPL-2730/0730 are specified at an input current of 1.6 mA and have a 7 V VCC and VO rating. The 300% minimum CTR allows TTL to TTL interfacing at this input current. Important specifications such as CTR, leakage current, and output saturation voltage are guaranteed over the 0°C to 70°C temperature range to allow trouble-free system operation. Selection for lower input currents down to 250 µA is available upon request.

DC CURRENT TRANSFER RATIO (CTR) is defined as the ratio of output collector current, IO, to the forward LED input current, IF, times 100%. 4. Device considered a two-terminal device: pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7, and 8 shorted together. 5. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together. 6. Common mode transient immunity in a Logic High level is the maximum tolerable (positive) dVCM /dt of the common mode pulse, VCM, to assure that the output will remain in a Logic High state (i.e., VO > 2.0 V). Common mode transient immunity in a Logic Low level is the maximum tolerable (negative) dVCM/dt of the common mode pulse, VCM, to assure that the output will remain in a Logic Low state (i.e., VO < 0.8 V). 7. In applications where dV/dt may exceed 50,000 V/µs (such as static discharge) a series resistor, RCC, should be included to protect the detector IC from destructively high surge currents. The recommended value is RCC = 110 Ω. 8. Use of a 0.1 µF bypass capacitor connected between pins 5 and 8 adjacent to the device is recommended. 9. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 3000 V rms for 1 second (leakage detection current limit, II-O < 5 µA). 10. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000 V rms for 1 second (leakage detection current limit, II-O < 5 µA). 11.
