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
electrical isolation between input and output. An
RMS
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.
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.
2 Peaking circuits may produce transient input currents up to 50mA, 50ns maximum pulse width,
provided average current does not exceed 20mA.
