Description
The ACPL-M50L (single-channel in SO-5 footprint),
ACPL-054L (dual-channel in SO-8 footprint), ACPL-W50L
(single-channel in stretched SO-6 footprint) and ACPL-
K54L (dual-channel in stretched SO-8 footprint) are low
power, low-input current, 1MBd digital optocouplers.
This 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-M50L/054L/W50L/K54L have an increased com-
mon mode transient immunity of 15kV/s minimum at
VCM = 1500V over a temperature range of -40 to 105°C.
The current transfer ratio (CTR) is 140% typical for ACPL-
M50L or 130% typical for ACPL-054L/W50L/K54L at IF
= 3mA. This digital optocoupler can be use in any TTL/
CMOS, TTL/LSTTL or wide bandwidth analog applications.

ACPL-054L/K54L
The connection of a 0.1 F bypass capacitor between pins 4 and 6 for
ACPL-M50L/W50L and between pins 5 and 8 for ACPL-054L/K54L is
recommended.
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.
