DESCRIPTION
The ICPL2611 optocoupler consists 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 ICPL2611 has an
internal shield which provides a common mode
transient immunity specification of 10000V/µs
typical.This unique design provides maximum ac
and dc circuit isolation while achieving TTL
compatibility. The coupled parameters are
guaranteed over the temperature range of -40°C to
+85°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

NOTES:-
1Bypassing 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.
2Peaking circuits may produce transient input currents up to 50mA, 50ns maximum pulse width,
provided average current does not exceed 20mA.
3Device considered a two terminal device; pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7
and 8 shorted together.
4The 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.
5The 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.
6The 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.
7The 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.
8CMH 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).
9CML 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.
