HIGH SPEED DUAL CHANNEL

OPTICALLY COUPLED ISOLATOR

PHOTOTRANSISTOR OUTPUT

APPROVALS

l UL recognised, File No. E91231

DESCRIPTION

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

electrical isolation

RMS

the 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.

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. Each channel .

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

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

8. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.

9. 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).

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

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

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