ICPL2730 ICPL2731 HIGH SPEED DUAL CHANNEL OPTICALLY COUPLED ISOLATOR PHOTODARLINGTON OUTPUT APPROVALS l UL recognised, File No. E91231 DESCRIPTION These dual channel diode-darlington optocouplers use a pair of light emitting diodes and an integrated high gain photon detectors to provide 2500Volts RMS electrical 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 photodarlington coupler by reducing the base-collector capacitance.

CURRENT TRANSFER RATIO is defined as the ratio of output collector current,IO , to the forward LED input current, IF times 100%. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together. 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).Measured in volts per microsecond (V/µs). 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).Measured in volts per microsecond (V/µs). Device considered a two-terminal device: pins 1,2,3, and 4 shorted together and pins 5,6,7 and 8 shorted together. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
