The LTC1380 is a single-ended 8-channel multiplexer, while the LTC1393 is a differential 4-channel multiplexer. The SMBus digital inter- face 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 synchro- nized with one stop bit. The supply current is typically 10 µA. Both digital interface pins are SMBus compatible over the full operating supply voltage range. The LTC1380 analog switches feature a typical RON of 35Ω (±5V supplies), typical switch leakage of 20pAandguaranteedbreak-before-makeoperation.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. s Micropower Operation: Supply Current = 20 µA Max s 2-Wire SMBus Interface s Single 2.7V to ±5V Supply Operation s Expandable to 32 Single or 16 Differential Channels s Guaranteed Break-Before-Make s Low RON: 35Ω Single Ended/70Ω Differential s Low Charge Injection: 20pC Max s Low Leakage: ±5nA Max s Available in 16-Lead SO and GN Packages FEATURES DESCRIPTION , LTC and LT are registered trademarks of Linear Technology Corporation.
