NOTES

1. Current Transfer Ratio is defined as a ratio of output collector current, IO, to the forward LED input current, IF, times 100%.

2. Pin 7 open. (6N138 and 6N139 only)

3. Common mode transient immunity in logic high level is the maximum tolerable (positive) dVcm/dt on the leading edge of the

common mode pulse signal, VCM, to assure that the output will remain in a logic high state (i.e., VO&2.0 V). Common mode

transient immunity in logic low level is the maximum tolerable (negative) dVcm/dt on the trailing edge of the common mode pulse

signal, VCM, to assure that the output will remain in a logic low state (i.e., VO'0.8 V).

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 shorted together.

5. For dual channel devices, CI-O is measured by shorting pins 1 and 2 or pins 3 and 4 together and pins 5 through 8 shorted together.

6. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
