A TOP level switch for use in a drive circuit in power-electronic systems having a half-bridge circuit formed by two power switches, a first so-called TOP switch and a second so-called BOT switch, which are arranged connected in series. The TOP level shifter transmits an input signal from drive logic to a TOP driver. In this case, the TOP level shifter is designed as an arrangement of an UP and a DOWN level shifter path, as well as a downstream signal evaluation circuit. In the associated method for transmission of this input signal, the signal evaluation circuit passes an output signal to the TOP driver when either the UP or the DOWN, or both, level shifter paths emit a signal to the respectively associated input of the signal evaluation circuit.
