Low Power, 1 MBd Digital Optocoupler
Data Sheet
Description
The Broadcom® 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, 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-M50L/054L/W50L/K54L has an increased common
mode transient immunity of 15 kV/μs minimum at V_CM = 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/W50L/K54L at I_F = 3mA. This digital
optocoupler can be used in any TTL/CMOS, TTL/LSTTL, or wide
bandwidth analog applications.
