HCPL-7601/7611
CMOS/TTL Compatible, Low Input Current, High Speed,
High CMR Optocoupler
Data Sheet
Description
The HCPL-7601/11 is a low input current version of the
HCPL-2601/11 and 6N137 (without enable). The
optically coupled gates combine an AlGaAs high-
efficiency light emitting diode and an integrated high
gain photon detector to create a low input current
device for low power applications. The output of the
detector IC is an open collector Schottky-clamped
transistor. The internal shield provides a guaranteed
common mode transient immunity specification of
10,000 V/µs (HCPL-7611).
This unique design provides maximum ac and dc
circuit isolation while achieving CMOS and TTL
compatibility. The optocoupler ac and dc operational
parameters are guaranteed from -40°C to 85°C with
no derating required allowing trouble free system
performance. This product is suitable for high speed
logic interfacing, input/output buffering, and
applications that require low input-current switching
levels.

CAUTION: The small device geometries inherent to the design of this bipolar component increase the
component’s susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static
precautions be taken in handling and assembly of this component to prevent damage and/or degradation
which may be induced by ESD.
