ICPL2631 ICPL2630
DUAL CHANNEL, HIGH CMR, VERY HIGH SPEED OPTICALLY COUPLED ISOLATOR LOGIC GATE OUTPUT
APPROVALS l UL recognised, File No. E91231 DESCRIPTION The ICPL2630 / ICPL2631 are dual channel optocouplers consisting of GaAsP light emitting diodes and high gain integrated photo detectors to provide 3500Volts RMS electrical isolation between input and output. The output of the detector I.C.'s are open collector Schottky clamped transistors. The ICPL2631 has an internal shield which provides a guaranteed common mode transient immunity specification of 1000V/s minimum.This unique design provides maximum ac and dc circuit isolation while achieving TTL compatibility. The coupled parameters are guaranteed over the temperature range of 0C to 70C, such that a maximum input signal of 5mA will provide a minimum output sink current of 13mA(equivalent to fan-out of eight gates) FEATURES l High speed - 10MBit/s l High Common Mode Transient Immunity 10kV/s typical l Logic gate output l ICPL2631 has improved noise shield for 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. APPLICATIONS l Line receiver, data transmission l Computer-peripheral interface l Data multiplexing l Pulse transformer replacement

NOTES:1 Bypassing of the power supply line is required, with a 0.01F ceramic disc capacitor adjacent to each isolator. The power supply bus for the isolator(s) should be seperate from the bus for any active loads. Otherwise a larger value of bypass capacitor (up to 0.1F) may be needed to supress regenerative feedback via the power supply. 2 The tPHL propagation delay is measured from the 3.75 mA level Low to High transition of the input current pulse to the 1.5V level on the High to Low transition of the output voltage pulse. 3 The tPLH propagation delay is measured from the 3.75mA level High to Low transition of the input current pulse to the 1.5V level on the Low to High transition of the output voltage pulse. 4 Device considered a two terminal device; pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7 and 8 shorted together. 5 Each channel. 6 Measured between pins 1 and 2 shorted together and pins 3 and 4 shorted together. 7 CMH is the maximum tolerable rate of rise of the common mode voltage to assure that the output will remain in a high logic state (ie Vout > 2.0V). 8 CML is the maximum tolerable rate of fall of the common mode voltage to assure that the output will remain in a low logic state (ie Vout < 0.8V)
