com ISO808A, ISO808A-1 Description The ISO808A, ISO808A-1, are galvanic isolated 8-channel drivers featuring a low supply current.
Each driver contains 2 independent galvanic isolated voltage domains (VCC and VDD for the Process and Control Logic stages, respectively).
The ICs are intended for driving any kind of load with one side connected to ground.
The Control Logic Stage features an 8-bit Output Status...
