ICPL4502 HIGH SPEED, NON BASE LEAD OPTICALLY COUPLED ISOLATOR PHOTOTRANSISTOR OUTPUT APPROVALS l UL recognised, File No. E91231 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.

Derate linearly above 70oC free air temperature at a rate of 1.6 mA/°C. Derate linearly above 70oC free air temperature at a rate of 0.9 mW/°C. Derate linearly above 70oC free air temperature at a rate of 1.0 mW/°C. CURRENT TRANSFER RATIO is defined as the ratio of output collector current,IO , to the forward LED input current, IF times 100%. Device considered a two-terminal device: pins 1,2,3, and 4 shorted together and pins 5,6,7 and 8 shorted together. 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). The 1.9kΩ load represents 1 TTL unit load of 1.6mA and the 5.6kΩ pull-up resistor. The frequency at which the a.c. output voltage is 3dB below the low frequency asymptote. 1. 2. 3. 4. 5. 6. 7. 8. 9.
