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/
µ
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 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 0.01
µ
F 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 0.1
µ
F) 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 t
PHL
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 t
PLH
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 t
EHL
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 t
ELH
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
CM
H
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
CM
L
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.
