Data Sheet
ACPL-M21L, ACPL-021L, ACPL-024L,
ACPL-W21L, ACPL-K24L
Low Power, 5-MBd Digital CMOS Optocoupler
Description
The 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.
