... Improved System Performance Reduced Board Space Reduced Power Consumption Improved Data Throughput To achieve TTL compatibility, low channel capacitances and fast switching times, the DG540 family is built on the Siliconix proprietary D/CMOS process. Each switch conducts equally well in both directions when on. DG540 PLCC ...
