6N137 ICPL2601 HIGH CMR, VERY HIGH SPEED OPTICALLY COUPLED ISOLATOR LOGIC GATE OUTPUT APPROVALS l UL recognised, File No. E91231 DESCRIPTION The 6N137 / ICPL2601 optocouplers consist of a GaAsP light emitting diode and a high gain integrated photo detector to provide 2500Volts RMS electrical isolation between input and output. An enable input allows the detector to be strobed. The output of the detector I.C. is an open collector Schottky clamped transistor. The ICPL2601 has an internal shield which provides a guaranteed common mode transient immunity specification of 1000V/µs 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 0°C to 70°C, 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/µs typical l Logic gate output l ICPL2601 has improved noise shield for superior common mode rejection l Options :10mm lead spread - add G after part no.

NOTES:1 Bypassing of the power supply line is required, with a 0.01µF 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 0.1µF) may be needed to supress regenerative feedback via the power supply. 2 Peaking circuits may produce transient input currents up to 50mA, 50ns maximum pulse width, provided average current does not exceed 20mA. 3 Device considered a two terminal device; pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7 and 8 shorted together. 4 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. 5 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. 6 The tEHL enable input propagation delay is measured from the 1.5V level on the Low to High transition of the enable input voltage pulse to the 1.5V level on the High to Low of the output voltage pulse. 7 The tELH enable input propagation delay is measured from the 1.5V level on the High to Low transition of the enable input voltage pulse to the 1.5V level on the Low to High of the output voltage pulse. 8 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). 9 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) 10 No external pull up is required for a high logic state on the enable input.
