ACPL-M61L/064L SPI Evaluation Board
Ultra Low Power 10MBd Digital CMOS Optocouplers
User’s Guide
Product Description
The ACPL-M61L (single-channel in SO-5 footprint) and
ACPL-064L (dual-channel in SO-8 footprint) are low power,
low input current, 10 MBd digital optocouplers. They are
designed to operate at V
DD
from 2.7 V to 5.5 V and I
DD
of
1.3 mA/ch max. The input LED can be driven with a low
input driving current of 1.6 mA.
The ACPL-M61/064L has a common mode transient
immunity of 20 kV/µs (min.) at V
CM
= 1000 V.
Applications
• Communication Interface: RS485, CANBus, I
2
C
• Microprocessor System Interfaces
• Digital isolation for A/D, D/A converstion

About Evaluation Board
The ACPL-M61L/064L evaluation board allows designers
to evaluate Avago digital optocouplers easily on a solder-
less breadboard.
The evaluation board contains one ACPL-064L and one
ACPL-M61L (orientated 180°) to provide a total of three
channels (two in the forward direction and one in the
reverse direction). This combination is well-suited for
isolation of most bus interfaces comprising of clock and
separate data in/out signals.
Users may balance the input current limiting resistance
between anode and cathode of each channel by replacing
the dummy 0-ohm resistors on the evaluation board. This
split resistor conguration improves the common mode
rejection performance of the optocouplers.
The schematic diagram of the evaluation board is as
shown in Figure 1. Top view of the evaluation board is
shown in Figure 2.
