Avago Technologies ACNT-H61L-000E User Manual
Evaluation Board for ACNW261L / ACNT-H61L
Ultra Low Power 10MBd Digital CMOS Optocouplers
User Guide
Introduction
The ACNW261L (single-channel 400mil DIP8) and ACNTH61L (single-channel Stretched SO8) are 10MBd CMOS
optocouplers. These optocouplers utilize the latest CMOS
IC technology to achieve outstanding performance with
very low power consumption. Basic building blocks are
high speed LEDs and CMOS detector ICs. Each detector incorporates an integrated photodiode, a high speed transimpedance amplier, and a voltage comparator with an
output driver.
Applications
• Digital eld bus isolation: CANBus, RS485, USB
• Microprocessor system interface
• DC/DC converter
• Servo Motor

About Evaluation Board
The ACNW261L / ACNT-H61L evaluation board allows designers to evaluate Avago digital optocouplers easily with
their system setup.
This evaluation board also suits other Avago digital optocouplers of similar package type. The top part of the
board caters for 400mil DIP8 package type while the bottom part of the board caters for 14.2mm Stretched SO8
type. For more information on all Avago digital optocouplers, you may refer to Avago Optoisolation Products Selection Catalog.
Features of the evaluation board as listed:
• Allows input peaking capacitor placement for speed
improvement evaluation
• Able to employ input split anode/cathode resistors for
improved CMR performance
• Board V-cut for separate evaluation of 400mil DIP8 and
VDD
