Ultra Low Power 10 MBd Digital CMOS Optocoupler
Data Sheet
Description
The ACPL-061L/ACPL-C61L/ACNW261L is an optically
coupled optocoupler that combines an AlGaAs light
emitting diode and an integrated high gain photo
detector addresses the low power need. The optocoupler
consumes extremely low power, at maximum 1.5 mA I_DD
per channel across temperature. The forward current is as
low as 1.6 mA to 4 mA and allows direct current drive by
most microprocessors.
These optocouplers support both 3.3 V and 5 V supply
voltage with guaranteed AC and DC operational parame-
ters from temperature range -40° C to +105° C. The output
of the detector IC is a CMOS output. An enable input
allows the detector output to be strobed. The internal
Faraday shield provides a guaranteed common mode
transient immunity specification of 20 kV/μs.
The CMOS output is slew-rate controlled and is designed
to allow the rise time and fall time to be controlled over a
wide range of the load capacitance.
This unique design provides maximum AC and DC circuit
isolation while achieving TTL/CMOS compatibility. These
optocouplers are suitable for high speed logic interfacing,
while consuming extremely low power.
