ICPL2533 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 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.

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 7.5kΩ load represents 1 LSTTL unit load of 0.36mA and a 20kΩ pull-up resistor. 11. The 4.7kΩ load represents 1 LSTTL unit load of 0.36mA and a 8.2kΩ pull-up resistor. 12. The 2500 VRMS / 1minute capability is validated by a factory 3.1k VRMS / 1 second dielectric test.
