Low Power, 5-MBd Digital CMOS Optocoupler
Data Sheet
Description
Features
Broadcom® ACPL-M21L (single-channel SO-5 package),
ACPL-021L (single-channel SO-8 package), ACPL-024L
(dual-channel SO-8 package), ACPL-W21L (single-channel
stretched SO-6 package), and ACPL-K24L (dual-channel
stretched 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 requirement for additional
waveshaping.
An internal shield on the ACPL-M21L/021L/024L/W21L/K24L
guarantees common mode transient immunity of 25 kV/μs at a
common-mode voltage of 1000V. The ACPL-x2xL optocouplers'
series operates from a 2.7V to 5.5V supply with guaranteed AC
and DC performance from an extended temperature range of
–40°C to +105°C.
CAUTION
Take normal static precautions in handling and
assembly of this component to prevent damage
and/or degradation that might be induced by
electrostatic discharge (ESD). The components
featured in this data sheet are not to be used in
military or aerospace applications or
environments.
