DESCRIPTION

These diode-transistor optocouplers use a light

emitting diode and an integrated photon detector to

provide 2500Volts RMS electrical isolation between

input and output. Seperate connection for 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.

FEATURES

lHigh speed - 1 MBits/s

lHigh Common Mode Transient

Immunity 1000V/µs

lTTL Compatible

l2 MHz Bandwidth

lOpen Collector Output

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.
