Description
The ACPL-K49U is a single channel, high temperature,
high CMR, 20 kBd digital optocoupler, configurable as
a low power, low leakage phototransistor, specifically
for use in industrial applications. The stretched SO-8
stretched package outline is designed to be compatible
with standard surface mount processes.
This digital optocoupler uses an insulating layer between
the light emitting diode and an integrated photo 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.
Avago R²Coupler isolation product provides with rein-
forced insulation and reliability that delivers safe signal
isolation critical in high temperature industrial applica-
tions
