Ultra Low Power 10MBd Digital CMOS Optocoupler

Currently Viewing:

ACPL-C61L Digital CMOS Optocoupler that combines a AlGaAs light emitting diode with a integrated high gain photo detector addresses low power needs. The optocoupler consumes extremely low power, at maximum 1.5mA IDD across temperature. The forward current is as low as 3mA and thus allows direct current drive by most microprocessors.

ACPL-C61L has internal clearance of 0.5 mm, and is UL recognized with isolation voltage of 5000 Vrms for 1 minute, and IEC/EN/DIN EN 60747-5-5 working insulation voltage VIORM of 1414 VPEAK for reinforced insulation.

ACPL-C61L supports both 3.3V and 5V supply voltages with guaranteed AC and DC operational parameters from –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.

ACPL-C61L is  suitable for high speed logic interfacing, while consuming extremely low power.

The ACPL-C61L Digtial CMOS Optocouplers are available in a stretched SO-8 package.
