ABSTRACT:
A symmetric adapter unit for switching a logic signal implemented in CMOS technology that includes a control module for transmission and non-transmission of the logic signal, receiving this logic signal and a control logic signal to deliver a first and a second asymmetric switching control signal. A bistable type switching module receives the first and the second switching control signal and delivers a logic signal adapted in phase with the logic signal or a substantially constant signal to the output terminal, constituting a high impedance output.
