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.

Fig. 14 Common Mode Transient Immunity Test Circuit and Waveform

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).
