6N138, 6N139 HIGH SPEED OPTICALLY COUPLED ISOLATOR PHOTODARLINGTON OUTPUT APPROVALS l UL recognised, File No. E91231 DESCRIPTION These diode-darlington optocouplers use a light emitting diode and an integrated high gain photon detector 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 photo-darlington coupler by reducing the base-collector capacitance. FEATURES l High speed - DC to 300kBits/s operation l High Common Mode Transient Immunity 10kV/s typical l TTL Compatible - 0.1V VOL typical l Base access allows Gain Bandwidth Adjustment l Low Input Current Requirement - 0.5mA l High Current Transfer Ratio - 2000% typ. l Open Collector Output l 2500V RMS Withstand Test Voltage, 1 min l 6N139 has improved noise shield which gives superior common mode rejection l Options :10mm lead spread - add G after part no.

Derate linearly above 50oC free air temperature at a rate of 0.7 mW/C. Derate linearly above 25oC free air temperature at a rate of 0.7 mA/C. Derate linearly above 25oC free air temperature at a rate of 2.0 mW/C. CURRENT TRANSFER RATIO is defined as the ratio of output collector current,IO , to the forward LED input current, IF times 100%. 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 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). 1. 2. 3. 4. 5. 6. 7. 8. 9.
