Only those products bearing the UL Certification Mark should be considered as being covered by UL'sCertification and Follow-Up Service.
The UL Recognized Component Mark generally consists of the manufacturer’s identification and catalog
number, model number or other product designation as specified under “Marking” for the particular
Recognition as published in the appropriate UL Directory. As a supplementary means of identifying productsthat have been produced under UL’s Component Recognition Program, UL’s Recognized Component Mark:, may be used in conjunction with the required Recognized Marks. The Recognized Component Mark is
required when specified in the UL Directory preceding the recognitions or under “Markings” for the individualrecognitions.
Recognized components are incomplete in certain constructional features or restricted in performancecapabilities and are intended for use as components of complete equipment submitted for investigation rather
than for direct separate installation in the field. The final acceptance of the component is dependent upon its
installation and use in complete equipment submitted to UL LLC.
Look for the UL Certification Mark on the product.

GENERAL:
This digital isolator offers a low-power, low-cost, high electromagnetic
interference (EMI) immunity, and stable temperature performance throughproprietary process technology. The device uses a monolithic solution toisolate different ground domains and block high-voltage/high-current
transients from sensitive or human interface circuitry. Four of the six
channels are unidirectional, two in each direction. All four unidirectional
channels support data rates of up to 50Mbps. The other two channels arebidirectional with data rates up to 2Mbps.
TECHNICAL CONSIDERATIONS (NOT FOR FIELD REPRESENTATIVE'S USE):
Use - For use only in products where the acceptability of the combination isdetermined by UL LLC.
USR indicates this product was investigated under the UL Standard for Safetyfor Optical Isolators, UL 1577, Fifth Edition, revised July 6, 2023.
