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. FEATURES l High speed - 1 MBits/s l High Common Mode Transient Immunity 1000V/s l TTL Compatible l 3 MHz Bandwidth l Open Collector Outputs l 2500V RMS Withstand Test Voltage,1 Min l ICPL2531 has improved noise shield which gives superior common mode rejection l Options :10mm lead spread - add G after part no. Surface mount - add SM after part no. Tape&reel - add SMT&R after part no. l All electrical parameters 100% tested l Custom electrical selections available APPLICATIONS l Line receivers l Pulse transformer replacement l Wide bandwidth analog coupling l Output interface to CMOS-LSTTL-TTL

Derate linearly above 70oC free air temperature at a rate of 0.8 mA/C. 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. Each channel . 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. Measured between pins 1 and 2 shorted together, and pins 3 and 4 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 1.9k load represents 1 TTL unit load of 1.6mA and the 5.6k pull-up resistor. The 4.1k load represents 1 LSTTL unit load of 0.36mA and the 6.1k pull-up resistor. The frequency at which the a.c. output voltage is 3dB below the low frequency asymptote.
