Description 

ACPL-M21L (single channel SO-5 package), ACPL-021L (single channel SO-8 package) and ACPL-024L (dual channel SO-8 package) are optically-coupled logic gates.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/021L/024L guarantees common mode transient immunity of 25 kV/ps at a common mode voltage of 1000 V. The ACPL-x2xL optocouplers' 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. Glitches free output upon power-up and power-down of optocou-pler.
