Abstract
An integrated circuit having logic circuits and a logic output buffer, which circuit includes the following sub-circuits: a memory circuit and a logic output circuit, in which no tri-state occurs at the output during a sequence of data signals at the input, wherein the drive of the circuit by means of control signals is not critical over time because the first data signal from the sequence switches off the tri-state mode, the tri-state mode again being introduced if a control signal is furnished, and in the absence of this control signal, the last data signal is retained.
