Description
The ISO1H801G 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 625 mA.
An 8 bit parallel µC compatible interface allows to
connect the IC directly to a µC system. The input
interface supports also a direct control mode and is
designed to operate with 5V CMOS compatible levels.
The data transfer from input to output side is realized by
the integrated Coreless Transformer Technology.
