Broadcom, ACPL-021L-500E CMOS Output Optocoupler, Surface Mount, 8-Pin SO

The Broadcom ACPL-021L (single channel SO-8 package) is the first industrial 5MBd low power digital optocoupler. The detector has CMOS output stage and optical receiver input stages with built-in Schmitt triggers to provide logic-compatible waveforms, eliminating the need for additional waveshaping. The optocoupler consumes extremely low power, at maximum 1.1mA IDD current per channel across temperature. With a forward LED current as low as 1.6 mA, most microprocessors can directly drive the LED.
