Description
The ISO1H816G is a galvanically isolated 8 bit data
interface in PG-DSO-36 package that provides 8 fully
protected high-side power switches that are able to
handle currents up to 1.2 A.
An serial µC compatible interface allows to connect the
IC directly to a µC system. The input interface is
designed to operate with 3.3/5V CMOS compatible
levels.
The data transfer from input to output side is realized by
the integrated Coreless Transformer Technology.
