1. Always design to the specified minimum/maximum electrical limits (where applicable).

2. Current Transfer Ratio (CTR) = IC/IF x 100%.

3. For this test, LED Pins 1 and 2 are common and Phototransistor Pins 4 and 5 are common.

4. Isolation Surge Voltage, VISO, is an internal device dielectric breakdown rating.

5. For test circuit setup and waveforms, refer to Figure 9.
