Abstract
An input voltage U.sub.IN to a voltage level converter 10 having a high input impedance charges a storage element which periodically discharges current to an LED 16 which periodically provides a light pulse for generating a level converted version of the input voltage U.sub.IN. A resistor R.sub.p 22 connected to the storage element allows the storage element to discharge noise voltage spikes in the input voltage U.sub.IN.
