... INFORMATION Standard 3-Wire Mode (Figure 3) Refer to the Serial Interface Operating Sequence in Figure 1. When operating in 3-wire mode, the LTC1329-10/ LTC1329-50/LTC1329A-50 will interface directly with most standard 3- or 4-wire serial interface systems. The clock (CLK) input synchronizes the data transfer with each input ...
