Broadcom ACPL-M21L Digital CMOS Optocouplers

Broadcom ACPL-M21L Digital CMOS Optocouplers feature a 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 1.6mA, most microprocessors can directly drive the LED. A superior internal shield on the Broadcom ACPL-M21L guarantees common mode transient immunity of 25kV/µs at a common mode voltage of 1000V over a temperature range of -40°C to 105°C. Glitches free output upon power-up and power-down of optocoupler. ACPL-M21L is ideal for use in a variety of applications, including industrial networking/IOs, isolation of high speed logic systems, and more.
