Data register with integrated signal level conversion

Abstract

Data register for storage of a data bit with integrated signal level conversion. The data register has an input for application of a data bit input signal which has a first voltage shift between a reference ground potential and a first voltage potential, a controllable switching device for passing on the applied data bit signal, a potential isolating transistor having a control connection at the first voltage potential, a first inverter which emits, in inverted form, the passed-on data bit input signal as a data bit output signal having a second voltage shift between the reference ground potential and a second supply potential, at one output of the data register for further data processing, and a second inverter, which feeds back the data output signal for storage of the data bit.
