ICPL2611
13/12/00
HIGH CMR, HIGH SPEED OPTO
ISOLATOR
DESCRIPTION
The ICPL 2611 consists of a GaAsP emitting diode and a
unique integrated detector. The photons are detected by a
photodiode and then amplified by a high gain linear
amplifier that drives a logic gate with a strobable output.
This output features a Schottky clamped open collector
output transistor. The circuit is temperature, current and
voltage compensated. This unique isolator design
provides maximum DC and AC circuit isolation between
input and output while achieving LSTTL/TTL circuit
compatibility. The isolator operational parameters are
guaranteed from 0°C to 70°C, such that a minimum input
current of 5 mA will sink an eight gate fan-out (13mA)
at the output with 5 volt Vcc supplied to the detector.
This isolation and coupling is achieved with a typical
propagation delay of 39ns. The enable input provides
gating of the detector with input sinking and sourcing
requirements compatible with LSTTL/TTL interfacing
and a propagation delay of 35ns typical.

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.

7 The t

8 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).
9 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)
10 For sinusoidal voltages dvCM = π fCMVCM(p-p)
11 No external pull up is required for a high logic state on the enable input.
12 DC current transfer ratio is defined as the ratio of the output collector current to the forward bias input
current times 100%.
