Data Sheet ACPL-M21L, ACPL-021L, ACPL-024L, ACPL-W21L, ACPL-K24L Low Power, 5-MBd Digital CMOS Optocoupler Description Features The Broadcom ACPL-M21L (single-channel SO-5 CMOS output package), ACPL-021L (single-channel SO-8 package), Wide supply voltage: 2.7V to 5.5V ACPL-024L (dual-channel SO-8 package), ACPL-W21L Low power supply current I : 1.1 mA/channel max. DD (single-channel stretched SO-6 package), and ACPL-K24L Low forward current I : 1.6 mA min. F (dual-channel stretched SO-8 package) are optically Speed: 5 MBd typ. coupled logic gates. The detector IC has CMOS output Pulse width distortion (PWD): 200 ns max. stage and optical receiver input stage with built-in Schmitt Propagation delay skew (tpsk): 220 ns max. trigger to provide logic-compatible waveforms, eliminating Propagation delay (tp): 250 ns max. the requirement for additional waveshaping. Common mode rejection: 25 kV/s min. at V = CM 1000V An internal shield on the ACPL-M21L/021L/024L/W21L/ Hysteresis: 0.2 mA typ. K24L guarantees common mode transient immunity of 25 kV/s at a common-mode voltage of 1000V. The Temperature range: 40C to +105C ACPL-x2xL optocouplers series operates from a 2.7V to Safety and regulatory approvals 5.5V supply with guaranteed AC and DC performance from UL 1577 recognized: 3750 V for 1 minute for RMS an extended temperature range of 40C to +105C. ACPL-M21L/021L/024L and 5000 V for 1 minute RMS for ACPL-W21L/K24L CAUTION Take normal static precautions in handling and CSA Approval assembly of this component to prevent damage IEC/EN 60747-5-5, Approval for Reinforced and/or degradation that might be induced by Insulation electrostatic discharge (ESD).
