1. Each channel, where appropriate.
2. Current Transfer ratio is defined as the ratio of output collector current, IO, to the forward LED input current, I
100%. CTR is known to degrade slightly over the unit’s lifetime as a function of input current, temperature, signal duty
cycle and system on time. It is recommended that designers allow at least 20-25% guard band for CTR degradation.
3. Measured between pins 1 through 8 shorted together, and pins 9 through 16 shorted together.
4. Measured between each input pair shorted together, and the output pins for that channel shorted together.
5. Measured between pins 3 and 4 shorted together, and pins 7 and 8 shorted together.
6. CM
remain in the logic high state (i.e., V
7. CM
remain in the logic low state (i.e., VO < 0.8V).
8. Bandwidth is the frequency at which the AC output voltage is 3dB below the low frequency asymptote.
9. This is a momentary withstand test, not an operating condition.
