Data communication system

摘要

A data communication system comprising: a plurality of electronic devices with the same or different internal CMOS voltages; an interconnection between two or more of the electronic devices; driver and receiver circuits which send and receive signals at a selectable communication voltage levels for interfacing between said two or more electronic devices, at a common communication voltage which is the lowest of the internal chip voltages; and means for configuring said selected voltage drivers and receivers. <IMAGE>
