Description
The 6N140A consists of four IR light emitting diodes, each optically coupled to a corresponding integrated high gain photon detector.
The high gain output stage features an open collector output providing both lower output saturation voltage and higher speed operation
than possible with a conventional photodarlington type coupler. The minimum CTR of 300% at an input current of 0.5mA makes it
ideal for use in low input current applications such as MOS, CMOS and low power logic interfacing or data transmission systems.
Surface Mount Option Available.

Notes
1. Pin 10 should be the most negative voltage at the detector side. Keeping Vcc as low as possible, but greater than 2.0V, will provide
lowest total Ioh over temperature.
2. Output Power is collector output plus one fourth of total supply power. Derate at 1.66mW/°C above 110°C.
3. Derate If at 0.33mA/°C above 110°C.
4. Each channel.
5. Current Transfer Ratio is defined as the ratio of output collector current Io to the forward LED input current If, times 100%.
6. Iohx is the leakage current resulting from channel to channel optical crosstalk. If=2µ
A for channel under test. For all other channels,
If=10mA.
7. Pins 1 through 8 shorted together and pins 9 through 16 shorted together.
8. Measured between LED anode and cathode shorted together and pins 10 through 15 shorted together.
9. Measured between adjacent input pairs shorted together (ie. pins 1 and 2 shorted together, and pins 3 and 4 shorted together, etc.)
10. CMh is the maximum tolerable common mode transient to assure that the output will remain in a high logic state (ie. Vo > 2.0V)
11. CMl is the maximum tolerable common mode transient to assure that the output will remain in a low logic state (ie. Vo < 0.8V)
12. In applications where dV/dt may exceed 50000V/µs (such as static a discharge), a series resistor Rcc should be included to protect
the detector ICs from destructively high surge currents. The recommended value is
Rcc=(1 V) / (0.6 If mA) kohm.
