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
input and output. The output of the detector I.C.'s

electrical isolation between

RMS

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)

FEATURES

l High speed - 10MBit/s

l High Common Mode Transient

Immunity 10kV/µs 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 0.01µF 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.
