Description

These high gain series couplers use a pair of light emitting diodes and integrated high gain photon detectors to provide 3000Vdc electrical insulation, 500V/µs common mode transient immunity and extremely high current transfer ratio between input and output. A separate pin for the photodiodes and first gain stages result in TTL compatible saturation voltages and high speed operation. Where desired, the Vcc and Vo terminals may be tied together to achieve conventional photodarlington operation. A base access terminal allows a gain bandwith adjustment to be made. Surface Mount Option Available.
All electrical parameters are 100% tested. Specifications are guaranteed to a cumulative 0.65% AQL.

Caution: The small junction sizes inherent to the design of this bipolar component increases the component's susceptibility to damage from electrostatic discharge. Normal static precautions should be taken in handling and assembly of this component to prevent damage or degredation.

Notes

  1. Derate linearly 0.5mA/°C above 50°C.
  2. Derate linearly 0.9mW/°C above 50°C.
  3. Derate linearly 0.6mA/°C above 35°C.
  4. Pin 5 should be the most negative voltage at the detector side.
  5. Derate linearly 1.7mW/°C above 35°C. Output power is collector power plus supply power.
  6. Each channel.
  7. DC Current Transfer Ratio is the ratio of output collector current Io to the forward LED input current If, times 100%.
  8. Device considered two-terminaled: pins 1,2,3,4 shorted together and pins 5,6,7,8 shorted together.
  9. Measured between pins 1,2 shorted together and pins 3,4 shorted together.
  10. Common mode transient immunity in Logic High (Low) Level is the maximum tolerable, positive (negative), dVcm/dt on the leading (trailing) edge of the common mode pulse signal, Vcm, to ensure that the output will remain in a Logic High (Low) state, ie. Vo>2.0V (Vo<0.8V).
  11. In applications where dVcm/dt may exceed 50000V/µs (such as static discharge), a series resistor Rcc should be included to protect the detector IC from destructively high surge currents. The recommended value is:

RCC=(1V / 0.3IF(mA)) kohm
