Description
Features
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 guar-
antees common mode transient immunity of 25 kV/µs
at a common mode voltage of 1000 V. The ACPL-x2xL
optocouplers' series operates from a 2.7 V 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.
