DESCRIPTION

These diode-darlington optocouplers use a light

emitting diode and an integrated high gain photon

detector to provide 2500Volts _RMSelectrical isolation

between input and output. Seperate connection for

the photodiode bias and output darlington collector

improve the speed up to a hundred times that of a

conventional photo-darlington coupler by reducing

the base-collector capacitance.

NOTES:-

Derate linearly above 50^oC free air temperature at a rate of 0.4 mA/°C.

Derate linearly above 50^oC free air temperature at a rate of 0.7 mW/°C.

Derate linearly above 25^oC free air temperature at a rate of 0.7 mA/°C.

Derate linearly above 25^oC free air temperature at a rate of 2.0 mW/°C.

CURRENT TRANSFER RATIO is defined as the ratio of output collector current,I_O, to the forward LED

input current, I_Fmultiplied by 100%.

Pin 7 open.

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

together.

Use of a resistor between pin 5 and 7 will decrease gain and delay time.

Common mode transient immunity in Logic High level is the maximum tolerable (positive) dVcm/dt on

the leading edge of the common mode pulse V_CMto assure that the output will remain in a Logic High

state (i.e. V_O> 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, V_CMto assure that the output

willremaininLogicLowstate(i.e.V_O<0.8V).
