Broadcom, ACPL-M417T-000E DC Input Transistor Output Optocoupler, Surface Mount, 4-Pin SO4

The Broadcom Optocoupler is a single channel low speed optocoupler with transistor output. It comes in a compact, surface mountable SO4 package for space savings. It provides an isolation voltage of 4kVRMS between input and output channels. It is primarily designed for low power operation, with low operating LED drive current of 0.3mA for low speed signalling. The low collector dark current effectively does not consume any current when the part is not in use.
