10 / 14 page 10 Notes: 1. Measured at a point 1.6 mm below seating plane. 2. Current into/out of any single lead. 3. Surge input current duration is 3 ms at 120 Hz pulse repetition rate. Transient input current duration is 10 µs at 120 Hz pulse repetition rate. Note that maximum input power, P IN, must be observed. 4. Derate linearly above 70°C free-air temperature at a rate of 4.1 mW/°C (HCPL-3700/3760) and 3.1 mW/°C (HCPL-0370). Maximum input power dissipation of 230 mW (HCPL-3700/3760) and 172 mW (HCPL-0370) allows an input IC junction temperature of 125°C at an ambient tempera- ture of T A = 70°C. Excessive PIN and TJ may result in IC chip degradation. 5. Derate linearly above 70°C free-air temperature at a rate of 5.4 mW/°C (HCPL-3700/3760) and 5 mW/°C (HCPL-0370). 6. Derate linearly above 70°C free-air temperature at a rate of 3.9 mW/°C (HCPL-3700/3760) and 1.9 mW/°C (HCPL-0370). Maximum output power dissipation of 210 mW (HCPL-3700/3760) and 103 mW (HCPL-0370) allows an output IC junction temperature of 125°C at an ambient temperature of T A = 70°C. 7. Derate linearly above 70°C free-air temperature at a rate of 0.6 mA/°C. 8. Maximum operating frequency is defined when output waveform Pin 6 obtains only 90% of V CC with RL = 4.7 kW, CL = 30 pF using a 5 V square wave input signal. 9. All typical values are at T A = 25°C, VCC = 5.0 V unless otherwise stated. 10. The t PHL propagation delay is measured from the 2.5 V level of the leading edge of a 5.0 V input pulse (1 µs rise time) to the 1.5 V level on the leading edge of the output pulse (see Figure 10). 11. The t PLH propagation delay is measured from the 2.5 V level of the trailing edge of a 5.0 V input pulse (1 µs fall time) to the 1.5 V level on the trailing edge of the output pulse (see Figure 10). 12. Common mode transient immunity in Logic High level is the maximum tolerable (positive) dV CM/dt on the leading edge of the common mode pulse, V CM, to insure that the output will remain in a Logic High state (i.e., VO > 2.0 V). Common mode transient immunity in Logic Low level is the maximum tolerable (negative) dV CM/dt on the trailing edge of the common mode pulse signal, VCM, to insure that the output will remain in a Logic Low state (i.e., V O < 0.8 V). See Figure 11. 13. In applications where dV CM/dt may exceed 50,000 V/µs (such as static discharge), a series resistor, RCC, should be included to protect the de- tector IC from destructively high surge currents. The recommended value for R CC is 240 ý per volt of allowable drop in VCC (between Pin 8 and V CC) with a minimum value of 240 ý. 14. Logic low output level at Pin 6 occurs under the conditions of V IN ž VTH+ as well as the range of VIN > VTH– once VIN has exceeded VTH+. Logic high output level at Pin 6 occurs under the conditions of V IN VTH- as well as the range of VIN < VTH+ once VIN has decreased below VTH-. 15. AC voltage is instantaneous voltage. 16. Device considered a two terminal device: Pins 1, 2, 3, 4 connected together, and Pins 5, 6, 7, 8 connected together. 17. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 4500 V rms for 1 second (leakage detection current limit, I i-o ≤ 5 µA). 18. 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, I i-o ≤ 5 µA). This test is performed before the 100% production test for partial discharge (Method b) shown in the IEC/ EN/DIN EN 60747-5-5 Insulation Characteristics Table. Figure 1.
