Broadcom, ACPL-K376-500E Open Collector Output Optocoupler, Surface Mount, 8-Pin

The Broadcom ACPL-K376 is voltage/current threshold detection opt couplers. The ACPL-K376 is a low current version of the ACPL-K370. To obtain lower current operation, the ACPL-K376 uses a high-efficiency AlGaAs LED which has higher light output at lower drive currents. Both devices have a threshold sensing input buffer IC that allows threshold levels to be set by a single external resistor over a wide range of input voltages.
