Abstract: At least one high voltage rated isolation capacitor is formed on a face of a primary integrated circuit die. The isolation capacitor AC couples the primary integrated circuit in a first voltage domain to a second integrated circuit in a second voltage domain. The isolation capacitor DC isolates the primary integrated circuit from the second integrated circuit die.

Abstract: A constant current output sink or source eliminates a current limiting series resistor for a light emitting diode (LED) and maintains a constant light intensity from the LED for all operating and manufacturing variables of a digital device since the current through the LED is maintained at a constant value. The constant current output sink or source may be programmable for selection of a constant current value from a plurality of constant current values available.
