Abstract: Described herein is an output buffer including an output stage formed by a pull-up transistor and a pull-down transistor, which are connected in series between a supply line set at a supply potential and a ground line set at a ground potential, with an intermediate node connected to the output of the output buffer. The output buffer further includes a unidirectional decoupling stage arranged between the output of the output buffer and the pull-up transistor for decoupling the output from the supply line during the switching transients of the output buffer in such a way as to prevent the switching noise present on the latter from being transferred onto the output of the output buffer.
