Broadcom ACPL-021L-060E

Broadcom's 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 optocoupled logic gates. The detector IC features a CMOS output stage and an optical receiver input stage with a built-in Schmitt trigger, providing logic-compatible waveforms without additional waveform shaping. The internal shield on the ACPL-M21L/021L/024L/W21L/K24L guarantees 25kV/μs common-mode transient immunity at 1000V common-mode voltage. The ACPL-x2xL optocoupler series operates at a supply voltage of 2.7V to 5.5V, with guaranteed AC and DC performance over an extended temperature range of -40°C to +105°C.
