Description

The LTC®1380/LTC1393 are CMOS analog multiplexers with SMBus® compatible digital interfaces. The LTC1380 is a single-ended 8-channel multiplexer, while the LTC1393 is a differential 4-channel multiplexer. The SMBus digital interface requires only two wires (SCL and SDA). Both the LTC1380 and the LTC1393 have four hard-wired SMBus addresses, selectable with two external address pins. This allows four devices, each with a unique SMBus address, to coexist on one system and for four devices to be synchronized with one stop bit. The supply current is typically 10µA. Both digital interface pins are SMBus compatible over the full operating supply voltage range. The LTC1380 analog switches feature a typical RON of 35ohms (±5V supplies), typical switch leakage of 20pA and guaranteed break-before-make operation. Charge injection is ±1pC typical. The LTC1380/LTC1393 are available in 16-lead SO and GN packages. Operation is fully specified over the commercial and industrial temperature ranges.
