DC to 1 Mbit/s operation
The 6N138 and 6N139 high gain series couplers use a Light Emitting Diode and
an integrated high gain photon detector to provide 3000Vdc electrical
insulation, 500V/µs common mode transient immunity and extremely high
current transfer ratio between input and output. Separate pins for the
photodiode and output stage result in TTL compatible saturation voltages and
high speed operation. Where desired, the Vcc and Vo terminals may be tied
together to achieve conventional photodarlington operation. A base access
terminal allows a gain bandwidth adjustment to be made. Surface Mount Option Available.
All electrical
parameters are 100% tested. Specifications are guaranteed to a cumulative 0.65%
AQL.

Caution: The small junction sizes inherent to the design of this bipolar component increases the component's susceptibility to damage from electrostatic discharge. Normal static precautions should be taken in handling and assembly of this component to prevent damage or degredation.

1. DC Current Transfer Ratio is the ratio of output collector current Io to
the forward LED current If, times 100%.
2. Pin 7 Open
3. Device
considered as two-terminaled: pins 1,2,3,4 shorted together and pins 5,6,7,8
shorted together.
4. Use of a resistor between pin 5 and 7 will decrease
gain and delay time.
5. CMh is the maximum tolerable common mode transient
to assure that the output will remain in a high logic state (ie. Vo > 2.0V).
CMl is the maximum tolerable common mode transient to assure that the output
will remain in a low logic state (ie. Vo < 0.8V).
6. In applications
where dV/dt may exceed 50000V/µs (such as static discharge) a series
resistor Rcc should be included to protect the detector IC from destructively
high surge currents. Recommended value:
RCC (kohm)=(1V)/(0.15 IF (mA))
