Data Sheet ACPL-M50L, ACPL-054L, ACPL-W50L, ACPL-K54L Low Power, 1 MBd Digital Optocoupler Description Features Wide supply voltage V : 2.7V to 24V CC The Broadcom ACPL-M50L (single-channel in SO-5 Low drive current: 3 mA footprint), ACPL-054L (dual-channel in SO-8 footprint), Open-collector output ACPL-W50L (single-channel in stretched SO-6 footprint), TTL compatible and ACPL-K54L (dual-channel in stretched SO-8 footprint) Compact SO-5, SO-8, stretched SO-6, and stretched are low power, low-input current, 1-MBd digital SO-8 package optocouplers. 15 kV/s high common-mode rejection at V = 1500V CM These digital optocouplers use an insulating layer between Guaranteed performance from temperature range: the light-emitting diode and an integrated photon detector to 40C to +105C provide electrical insulation between input and output. Low propagation delay: 1 s max at 5V Separate connections for the photodiode bias and output Worldwide safety approval: transistor collector increase the speed up to a hundred UL1577 recognized, 3750 V /1 min for ACPL- rms times over that of a conventional photo-transistor coupler by M50L/054L, 5000 V /1 min for ACPL-W50L/K54L rms reducing the base-collector capacitance. CSA Approval IEC/EN/DIN EN 60747-5-5 Approval for Reinforced The ACPL-M50L/054L/W50L/K54L has an increased Insulation common mode transient immunity of 15 kV/s minimum at V = 1500V over a temperature range of 40C to +105C. CM The current transfer ratio (CTR) is 140% typical for Applications ACPL-M50L or 130% typical for ACPL-054L/W50L/K54L at Communications interface I = 3 mA. This digital optocoupler can be used in any F Digital signal isolation TTL/CMOS, TTL/LSTTL, or wide bandwidth analog Micro-controller interface applications. Feedback elements in switching power supplies CAUTION Take normal static precautions in handling and Digital isolation for A/D, D/A conversion digital field assembly of this component to prevent damage and/or degradation that might be induced by electrostatic discharge (ESD).
