Data output buffer with precharge

摘要

A data output buffer includes an output node, and a first stage connected to the output node for providing a first control signal for precharging the output node to an intermediate voltage with respect to a voltage for switching the output node from a current logic state to a different logic state. A second stage is connected to the first stage and to the output buffer. The first and second stages are responsive to a second control signal for enabling output of new data. A precharge logic circuit precharges the output node to the intermediate voltage as a function of data last output, and as a function of first and second reset signals until a rising and falling edge of the data last output respectively crosses the intermediate voltage.
