Notes (Apply typically to 16 pin package)
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, IF, times
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. CMH is the steepest slope (dV/dt) on the leading edge of the common mode pulse, VCM, for which the output will
remain in the logic high state (i.e., VO > 2.0V).
7. CML is the steepest slope (dV/dt) on the trailing edge of the common mode pulse, VCM, for which the output will
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.
