The Broadcom ACPL series 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.

Ultra low current IDD consumption
Built-in slew-rate controlled output
Tristate output with enable pin VE
