Description
The ACPL-M49U is a single channel, high temperature,
high CMR, 20kBd digital optocoupler, configurable as a
low power, low leakage phototransistor, specifically for
use in industrial applications. The SO-5 JEDEC registered
(MO-155) package outline is surface mountable.
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 in a 5-pin configuration increase
the speed up to a hundred times over that of a conven-
tional phototransistor by reducing the base-collector
capacitance. Common connections with the supply and
output pins shorted in a 4-pin configuration delivers low
power, low leakage performance as a phototransistor. The
ACPL-M49U has an increased common mode transient
immunity of 15kV/s minimum at VCM = 1500V over
extended temperature range.
Avago R2Coupler isolation products provide the rein-
forced insulation and reliability needed for critical in high
temperature industrial applications.

Note: The connection of a 0.1 F bypass capacitor
between pins 4 and 6 is recommended for 5-pin
configuration
Note: Pins 5 and 6 are externally shorted for 4-pin
configuration.
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.
