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/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)

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
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.

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)
