The Broadcom ACPL-061L 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 IDD 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.

Ultra low current IDD consumption 15 mA max
Low input current capability 16 mA min (ACPL-061L), 3 mA min (ACPL-C61L), 4 mA min (ACNW261L)
Available packages SO-8, Stretched SO-8 and 400 mil widebody
Built-in slew-rate controlled output
Tri-state output with enable pin VE
20 kV/μs minimum Common Mode Rejection (CMR) at VCM = 1000 V
High Speed 10 MBd min
Guaranteed AC and DC performance over wide temperature -40° C to +105° C
