Description
The 6N138 and 6N139 devices each consists of an infrared
emitting diode, optically coupled to a high gain split Darlington
photo detector. They provide extremely high current transfer
ratio between input and output, with access to a base terminal
to adjust the gain bandwidth.
Schematic
These devices are packaged in an 8-pin DIP package
and available in wide-lead spacing and SMD options.

Note:
*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 > 2.0V).
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 < 0.8V).
