... U APPLICATIONS INFORMATION Theory of Operation The LTC1380/LTC1393 are analog input multiplexers with an SMBus digital interface. The LTC1380 is a single-ended 8-to-1 multiplexer; the LTC1393 is a differential 4-to-1 mulitplexer. The LTC1380 operates on either bipolar or unipolar supplies, the LTC1393 operates on a single supply. The minimum V supply for the LTC1380/LTC1393 ...

... Both the LTC1380 and the LTC1393 have an enable bit (EN). A Low disables all switches while a High enables the selected switch as programmed by bits C2, C1 and C0. A stop bit after a successful send byte sequence for LTC1380/ LTC1393 will disable all switches before the new selected switch is connected. ...
