Datasheet

MAX3480EA/MAX3480EB
driven through a series current-limiting resistor.
Directly grounding these pins destroys the device.
Reliability
These products contain transformers, optocouplers,
and capacitors, in addition to several monolithic ICs
and diodes. As such, the reliability expectations more
closely represent those of discrete optocouplers, rather
than the more robust characteristics of monolithic sili-
con ICs. The reliability testing programs for these multi-
component devices may be viewed on the Maxim
website (www.maxim-ic.com) under Technical Support,
Technical Reference, Multichip Products.
