Description
The ACPL-K43T is a single channel, high temperature,
high CMR, high speed digital optocoupler in an eight lead
miniature footprint specifically used in the automotive
applications. The ACPL-K44T is a dual channel equiva-
lent of the ACPL-K43T. Both products are available in the
stretched SO-8 package outline, designed to be compat-
ible 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 products provide with rein-
forced insulation and reliability that delivers safe signal
isolation critical in automotive and high temperature
industrial applications.
