Notes:
1. Current Transfer Ratio is defined as a ratio of output collector current, I
2. Pin 7 open. (6N138 and 6N139 only)
3. Common mode transient immunity in logic HIGH level is the maximum tolerable (positive) dV
4. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are
5. For dual channel devices, C
6. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
