Notes:
1. Current Transfer Ratio is defined as a ratio of output collector current, I
O
, to the forward LED input current,
I
F
, times 100%.
2. Pin 7 open. (6N138 and 6N139 only)
3. Common mode transient immunity in logic HIGH level is the maximum tolerable (positive) dV
cm
/dt on the
leading edge of the common mode pulse signal V
CM
, to assure that the output will remain in a logic HIGH state
(i.e., V
O
> 2.0V). Common mode transient immunity in logic LOW level is the maximum tolerable (negative)
dV
cm
/dt on the trailing edge of the
common mode pulse signal, V
CM
, to assure that the output will remain in a logic LOW state (i.e., V
O
< 0.8V).
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, C
I-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.
