All minimum and maximum specifications are at recommended operating condition. Notes: 1) A.1µF or bigger bypass capacitor for VCC is needed. 2) Peaking driving circuit may be used to speed up the LED. The peak drive current of LED may go up to 5mA and maximum pulse width 5ns, as long as average current doesn t exceed 2mA. 3) tplh (propagation delay) is measured from the 3.75 ma point on the falling edge of the input pulse to the 1.5 V point on the rising edge of the output pulse. 4) tphl (propagation delay) is measured from the 3.75 ma point on the rising edge of the input pulse to the 1.5 V point on the falling edge of the output pulse. 5) CMH is the maximum tolerable rate of rise of the common mode voltage to assure that the output will remain in a high logic state (i.e., VO > 2. V). 6) CML is the maximum tolerable rate of fall of the common mode voltage to assure that the output will remain in a low logic state (i.e., VO <.8 V). 7) Device is considered a two-terminal device: pins 1, 2, 3 shorted together, and pins 4, 5, 6 shorted together. 8) In accordance with UL1577, each optocoupler is proof tested by applying an insulation test voltage 6 Vrms for one second (leakage current less than 1 ua). This test is performed before the 1% production test for partial discharge 9/16 Part No. :
