VMEbus(TM), one of the most widely used backplanes in the industry, has generated numerous end products by using third-party boards, mechanical hardware, software, and backplane driver chips. The VME double-edged source-synchronous transfer (2eSST) protocol needs an I/O driver to transmit signals along the VMEbus at significantly higher speeds than those achievable with the VME64 standard.

Many telecom and networking applications require that cards be inserted and extracted from a live backplane without interrupting data or damaging components. To achieve this interface terminals of the card must be electrically isolated from the bus system during insertion or extraction from the backplane. To facilitate this Texas Instruments provides bus-interface and logic devices with features
