6N138, 6N139
Single Channel, High Speed Optocouplers
Description
Dec.2008
These high gain series couplers use a light
emitter diode and an integrated high gain
photo detector to provide extremely high
current transfer ratio between input and
output. Separate pins for the photodiode and
output stage result in TTL compatible
saturation voltage and high speed operation.
Where desired the Vcc and Vo terminals
may be tied together to achieve conventional
photo darlington operation. A base access
terminal allows a gain bandwidth adjustment
to be made.

Notes,
1. AC For 1 Minute, R.H. = 40 ~ 60%. Isolation voltage shall be measured using the following method.
(1) Short between anode and cathode on the primary side and between collector and emitter on the secondary
side.
(2) The isolation voltage tester with zero-cross circuit shall be used.
µA
VRMS
Ω
(3) The waveform of applied voltage shall be a sine wave.
2. For 10 Seconds
3. Current Transfer Ratio (CTR) is defined as the ration of output collector current, Io, to the forward LED
input current, IF, times 100%.
4. Pin 7 open.
5. Instantaneous common mode rejection voltage "output (1)" represents a common mode voltage variation that can
hold the output above (1) level (Vo>2.0V).Instantaneous common mode rejection voltage "output (0)" represents a
common mode voltage variation that can hold the output above (0) level (Vo<0.8V).
6. Device considered a two terminal device. Pins 1, 2, 3 and 4 shorted together and Pins 5, 6, 7 and 8 shorted together.
