ACPL-M21L 5 MBd Optocoupler

Broadcom's ACPL-M21L is an optically-coupled logic gate. The detector IC has CMOS output stage and optical receiver input stage with built-in Schmitt trigger to provide logic-compatible waveforms, eliminating the need for additional waveshaping. An internal shield on the ACPL-M21L guarantees common mode transient immunity of 25 kV/µs at a common mode voltage of 1000 V. The ACPL-x2xL optocoupler series operates from a 2.7 to 5.5 V supply with guaranteed AC and DC performance from an extended temperature range of -40°C to 105°C, and glitch-free output upon power-up and power-down of the optocoupler.
