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
