6N135, 6N136

HIGH SPEED OPTICALLY

COUPLED ISOLATOR

PHOTOTRANSISTOR OUTPUT

APPROVALS

l UL recognised, File No. E91231

DESCRIPTION

These diode-transistor optocouplers use a light
emitting diode and an integrated photon detector to
provide 2500Volts
input and output. Seperate connection for the

electrical isolation between

RMS

photodiode bias and output transistor collector
improve the speed up to a hundred times that of a
conventional photo-transistor coupler by reducing
the base-collector capacitance.

FEATURES

l High speed - 1 MBits/s

l High Common Mode Transient

Immunity 1000V/µs

l TTL Compatible

l 2 MHz Bandwidth

l Open Collector Output

l 2500V

l 6N136 has improved noise shield which

Withstand Test Voltage,1 Min

RMS

gives superior common mode rejection

l Options :-

10mm lead spread - add G after part no.
Surface mount - add SM after part no.
Tape&reel - add SMT&R after part no.

NOTES:-

1. Derate linearly above 70oC free air temperature at a rate of 0.8 mA/°C.

2. Derate linearly above 70oC free air temperature at a rate of 1.6 mA/°C.

3. Derate linearly above 70oC free air temperature at a rate of 0.9 mW/°C.

4. Derate linearly above 70oC free air temperature at a rate of 1.0 mW/°C.

5. CURRENT TRANSFER RATIO is defined as the ratio of output collector current,IO , to the forward LED
input current, IF times 100%.

6. Device considered a two-terminal device: pins 1,2,3, and 4 shorted together and pins 5,6,7 and 8 shorted
together.

7. Common mode transient immunity in Logic High level is the maximum tolerable (positive) dVcm/dt on
the leading edge of the common mode pulse 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 Logic Low state (i.e. VO< 0.8V).

8. The 1.9kΩ load represents 1 TTL unit load of 1.6mA and the 5.6kΩ pull-up resistor.

9. The 4.1kΩ load represents 1 LSTTL unit load of 0.36mA and the 6.1kΩ pull-up resistor.

10. The frequency at which the a.c. output voltage is 3dB below the low frequency asymptote.
