ACPL-K54L-560E

ACPL-K54L-560E is a low power, 1MBd digital optocoupler. This digital optocoupler uses 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. Applications include communications interface, digital signal isolation, micro-controller interface, feedback elements in switching power supplies, digital isolation for A/D, D/A conversion digital field. Worldwide safety approvals include UL1577 recognized, 3750Vrms/1 min for ACPLM50L/054L, 5000 Vrms/1 min for ACPL-W50L/K54L, CSA approval, IEC/EN/DIN EN 60747-5-5 approval for reinforced insulation.
