Abstract
An integrated circuit includes a core circuit and a buffer circuit. The buffer circuit includes a plurality of input buffers and a plurality of output buffers that service a plurality of voltage domains on a single set of input/output lines. These voltage domains are controllable to service multiple voltage levels, consistent with various interface standards. In one construction, the core circuit operates at 1.2 volts and the buffer circuit supports both a 1.2 volts interface standard and a 3.3 volts interface standard.
