Description
Features
The ACPL-M50L (single-channel in SO-5 footprint), Wide supply voltage Vcc: 2.7V to 24V
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
Low Drive Current: 3mA
Open-Collector Output
power, low-input current, 1MBd digital optocouplers.
TTL compatible
Compact SO-5, SO-8, stretched SO-6 and stretched
This digital optocouplers use an insulating layer between
thelightemittingdiodeandanintegratedphotondetector
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.

Guaranteed performance from Temperature Range:
-40°C to +105°C
Low Propagation Delay: 1s max at 5V
Worldwide Safety Approval:
The ACPL-M50L/054L/W50L/K54L have an increased com-
(Pending except ACPL-M50L)
mon mode transient immunity of 15kV/s minimum at

CM
3750Vrms/1min for ACPL-M50L/054L,
5000Vrms/1min for ACPL-W50L/K54L,
The current transfer ratio (CTR) is 140% typical for ACPL-
M50L or 130% typical for ACPL-054L/W50L/K54L at I

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.
