1. Description

The Broadcom® ACPL-054L-560E (dual-channel in SO-8 footprint),  are low power, low-input current, 1-MBd digital optocouplers. These digital optocouplers use an insulating layer between the light-emitting diode and an integrated photon detector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output transistor collector increase the speed up to a hundred times over that of a conventional photo-transistor coupler by reducing the base-collector capacitance. The ACPL-054L-560E has an increased common mode transient immunity of 15 kV/µs minimum at VCM = 1500V over a temperature range of –40°C to +105°C. The current transfer ratio (CTR) is 140% typical for ACPL-M50L or 130% typical for ACPL-054L-560E at IF = 3 mA. This digital optocoupler can be used in any TTL/CMOS, TTL/LSTTL, or wide bandwidth analog applications.
